RF Frequency Converters Specifications

Performance


	Input Frequency Range		The range of input frequencies that the converter is designed to operate.
	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.

	Output Frequency Range		The range of output frequencies that the converter is designed to deliver.
	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.

	Conversion Gain		Conversion gain is the net increase in power between the fundamental input signal and the desired output. It is calculated as the ratio (in dB) of the output power to the RF input power. It is a measure of the efficiency of the converter in providing frequency translation between the input RF signal and the output signal.
	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.

	Return Loss		Output Return Loss is simply the amount of power that is "lost" to the load and does not return as a reflection. Input Return Loss is the amount of power that is "lost" to the converter and does not return back to the source. Clearly, high return loss is usually desired even though "loss" has negative connotations. Return loss is commonly expressed in decibels. For example, if one-half of the power does not reflect from the load/source, the return loss is 3 dB. Return Loss can also be expressed in terms of VSWR.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Noise Figure		The Noise Figure (NF) is the ratio (in dB) of the signal-to-noise ratio at the input of the component and the signal-to-noise ratio measured at the output. It is a measure of the amount of noise added to the signal during normal operation. A low noise figure means better performance. The NF value sets the lower limit of the Dynamic range of the amplifier.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

	Power Output		The maximum output signal power of the converter (expressed in dBm).
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Step Size		The minimum output frequency change that the converter can achieve.
	Search Logic:		All matching products will have a value less than or equal to the specified value.

Features


	Connectors
	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 50 and 75 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 50 or 75 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 50 impedance, but 75 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.
	Other		Other unlisted connector types.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Alarms and Status Indicators		The converter has indicators to signal important operating status or warnings.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Remote Control Interface		The converter has a port or interface that can be used to connect to a computer for remote operation and monitoring.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Frequency Inversion		Frequency inversion is the process of inverting a signal frequency to produce a mirror image at a different frequency range. This is one of the most common scrambling methods. This process relocates the power level of each input frequency to a new position, calculated as the difference between the original frequency and the inversion frequency.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Operating Temperature:		This is the full required range of ambient operating temperature.
	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.
