Device Type / Package
   Synthesizer Type       
   Your choices are...
  		      
 
   Integer-N
  		     In a standard PLL synthesizer the value of N, by which the output frequency is divided in order to compare it with the reference frequency, must always be an integer. In this type of synthesizer the resolution (step size) is equal to the reference.

 
 
   Fractional-N
  		     In a fractional-N PLL synthesizer the output frequency can be divided by a non-integer, allowing step sizes smaller than the reference.
 
   Other
  		     Other, not listed, PLL synthesizers.

   Package Type       
   Your choices are...
  		      
 
   Surface Mount Technology (SMT)
  		     Surface mount technology (SMT) adds components to a printed circuit board (PCB) by soldering component leads or terminals to the top surface of the board. SMT components have a flat surface that is soldered to a flat pad on the face of the PCB. Typically, the PCB pad is coated with a paste-like formulation of solder and flux. With careful placement, SMT components on solder paste remain in position until elevated temperatures, usually from an infrared oven, melt the paste and solder the component leads to the PCB pads.  

Industry-standard pick-and-place equipment can mount SMT components quickly, accurately, and cost-effectively. SMT is a widely used alternative to mounting processes that insert pins or terminals through holes and solder leads into place on the opposite side of the board.
 
   Flat Pack (FPAK)
  		     Flat pack (FPAK).
 
   Through Hole Technology (THT)
  		     Through hole technology (THT) mounts components on a printed circuit board (PCB) by inserting component leads through holes in the board and then soldering the leads in place on the opposite side of the board.
 
   Connectorized
  		     Connectorized devices attach with coaxial or other types of connectors.
 
   Waveguide Assembly
  		     Waveguide assemblies are used in microwave waveguide systems. They consist of a hollow metallic conductor with a rectangular, elliptical, or circular cross-section. Some conductors contain solid or gaseous dielectric materials.
 
   Other
  		     Other unlisted package types.

   RF Connector       
   Your choices are...
  		      
 
   BNC
  		     Bayonet Neil-Concelman (BNC) connectors were designed for military applications, but are used widely in video and RF applications to 2 GHz. BNC connectors have a slotted outer conductor and a plastic dielectric that causes increasing losses at higher frequencies. BNC connectors are usable above 4 GHz as long as the slots radiate signals; however, these devices may not be mechanically stable to 10 GHz. Both 50Omega: Ohms  and 75Omega: Ohms BNC connectors are available. BNC connectors are also known as bayonet navy connectors or baby Neil connectors.
 
   MCX
  		     Miniature coaxial (MCX) connectors provide broadband capability through 6 GHz and are used in applications where weight and physical space are limited. They provide good electrical performance and are used to address the rapid implementation of the U.S. digital cellular PCN infrastructure. MCX connectors are also used in global positioning systems (GPS) and wireless LAN  (WLAN) applications.
 
   Mini-UHF
  		     Mini-UHF connectors are a miniature version of the original UHF connector. They feature a threaded coupling mechanism for reliable mating. Mini-UHF connectors are designed for use in cellular mobile telephone systems where size, weight and cost are critical. With crimp cable termination for low installation costs, these connectors provide excellent RF performance in applications through 2.5 GHz.
 
   MMCX
  		     Micro-miniature coaxial (MMCX) connectors are smaller than MCX connectors and feature a more robust interface for greater durability. They are ideal for high volume, wireless SMT or PCMCIA applications in cellular base stations, cellular phones and personal communicators. MMCX connectors are also used in global positioning systems and wireless LAN (WLAN) applications.
 
   SMA
  		     Subminiature-A (SMA) connectors are intended for use on semi-rigid cables in components. They directly interface the cable dielectric without air gaps.  They are not intended for permanent connections.
 
   SMB
  		     Subminiature-N (SMB) connectors are snap-mount connectors that are available either in 50Omega: Ohms or 75Omega: Ohms impedances.  They are used for frequencies from DC to 4GHz.
 
   SMP
  		     Subminiature P (SMP) connectors are rated to 40 GHz and, depending on detent type, can withstand from 100 to 1,000 interconnect cycles.
 
   TNC
  		     Threaded Neil-Concelman (TNC) connectors are similar in size to BNC connectors but feature a threaded coupling nut for applications that require performance to 11 GHz. TNC connectors are durable, reliable devices that are widely used in the cellular and mobile communication industry for equipment cabling and antenna interfaces.
 
   Type F
  		     Type F connectors have a screw-type coupling and frequency range up to 1.5 GHz. Applications include CATV, TV, and antennas.
 
   Type N
  		     Type N connectors include an integrated gasket to protect against environmental ingress and create an air gap between the center and the outer conductor. They primarily have 50Omega: Ohms impedance, but 75Omega: Ohms versions for CATV, are available.
 
   UHF
  		     Ultra high frequency (UHF) connectors are economical, all-purpose connectors designed with non-constant impedance for use in comparatively low voltage and low frequency applications such as citizens' band (CB) communications systems. UHF connectors are also used in public address systems, closed circuit television (CCTV), civil defense, landing systems, ground control apparatus, ship-to-shore communications, and mobile radio equipment hookups between antenna and transmitters or receivers.
 
   1.6 / 5.6
  		     1.6 / 5.6 connectors are mechanically sturdy devices that feature a coupling mechanism. They are often used with equipment that requires resistance against environmental and mechanical stress. 1.6 / 5.6 connectors are also suitable for handling RF analog and digital signals in telecommunications systems.
 
   7-16
  		     7-16 connectors are designed for use in medium to high power communication systems. These connectors perform exceptionally well in multichannel cellular systems where power levels approximate 100 watts per channel. Designed for both flexible as well as corrugated cables, these connectors are used in a variety of cellular base station and broadcast communication applications.
 
   Other
  		     Other unlisted RF connectors.

Performance Specifications
   Frequency Range
  		     The range of frequencies that the synthesizer can accomplish.
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Step Size
  		     The minimum output frequency change that the synthesizer can achieve.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Settling Time
  		     The maximum amount of time needed to the output signal to reach its final (stable) state.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Output Power
  		     The power, specified in dBm, of the output signal measured into a 50 ohms load.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Phase Noise (@ 10kHz)
  		     Phase noise is the short term random fluctuations of the phase of a signal. Phase noise is particularly important in oscillators because this value is directly related to the frequency stability of the output signal. Phase noise is measured (in dBc/Hz) at different offset frequencies from the carrier frequency. Typically, phase noise is measured at offset frequencies of 1 kHz or 10 kHz, from the carrier frequency.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
