RF Modulation


	Modulation
	Your choices are...
	Amplitude Modulation (AM)		Amplitude modulation (AM) causes the baseband signal to vary the amplitude or height of the carrier wave to create the desired information content.
	Frequency Modulation (FM)		Frequency modulation (FM) causes the instantaneous frequency of a sine wave carrier to depart from the center frequency by an amount proportional to the instantaneous value of the modulating signal.
	On-Off Key (OOK)		On-off key (OOK) modulation consists of turning the signal on or off. This is the simplest form of modulation.
	Amplitude Shift Key (ASK)		Amplitude shift key (ASK) transmits data by varying the amplitude of the transmitted signal.
	Frequency Shift Key (FSK)		Frequency shift key (FSK) is a digital modulation scheme using two or more output frequencies.
	Phase Shift Key (PSK)		Phase shift key (PSK) is a digital modulation scheme in which the phase of the transmitted signal is varied in accordance with the baseband data signal.
	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.

	Radio Technique		Radio techniques limit localized interference and noise.
	Your choices are...
	Direct-Sequence Spread Spectrum		Signals are spread over a large band by multiplexing the signal with a code or signature that modulates each bit.
	Frequency-Hopping Spread Spectrum		Signals move through a narrow set of channels in a sequential, cyclical, and predetermined pattern. Devices avoid interference by not remaining in the same channel for a long period of time.
	Other		Other unlisted modulation techniques.
	Other		Other unlisted radio techniques such as infrared, narrowband, etc.
	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.

	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 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.
	RSMA		Reverse SMA (RSMA) connectors have reverse polarity.
	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.
	RTNC		Reverse TNC (RTNC) connectors have reverse polarity.
	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, specialized, or proprietary connectors.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	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.
