	Form Factor / Package
	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) devices have gull wing or flat leads on two or four sides. They provide exceptional thermal and electrical performance and are available in cavity-up and cavity-down configurations. Flat pack devices are typically ceramic, hermetic, and surface-mounted. They are available in a variety of body sizes and pin counts.
	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.
	Stand Alone		Devices are bench top or floor-standing units with a full casing or cabinet and an integral interface.
	Rack Mount		Devices mount in racks and come with hardware such as rail guides, flanges, or tabs. Some rack-mounted devices fit in a standard 19” telecommunications rack.
	Other		Other unlisted form factors or packages.
	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 50Ω and 75Ω 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 50Ω or 75Ω 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 50Ω impedance, but 75Ω 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.
