Terminations & Loads
We have more than 40,000 rf & microwave coaxial terminations in stock we can ship today. We offer these Microwave & RF terminations: SMA Terminations, Type N terminations, 7/16 DIN terminations, 2.92mm terminations, 2.4mm terminations, TNC terminations, smp terminations, minismp terminations, 4.1/9.5 minidin terminations. 4.3/10 terminations, ssma terminations, ssmc terminations, and a few Reverse Polarity terminations. Power levels of 0.5-150 watts. RF / Microwave terminations are also known as dummy loads or 50 ohm dummy loads. Our 1.85mm terminations, are rated to 67ghz. We offer 1.0mm terminations good to 110Ghz.

Adapters
We have more than 1000 types of coaxial adapters on the shelf for immediate delivery; more than 200,000 coaxial adapters total. SMA, Standard N, SMP, TNC, BNC etc adapters are built to M39012, Mil-STD883 (Interface) & MIL-G-45204 or ASTM B488(plating). 2.4mm, 2.92mm, 1.85mm, 1.0mm, 7/16, 3.5mm, Precision N, Precision TNC, & 4.3/10 adapters are built to P287. 4,1/9.5 adapters are built to IEC standards. There are a few popular coaxial adapters for which we're not aware of a standard; u.fl etc. Mini DIN adapters are in stock.

Pick-Off T's
Pick Off T's are popular in the Fiber Optic industry and are used to sample a signal.

Waveguides
A waveguide attenuator is an RF device specifically designed to reduce the power of a signal without affecting or reducing the waveform of the signal.

Dust Caps, Opens
These coaxial dust caps are used for protective purposes, both from the environment & contaminants. Note: SMA, 2.92, 3.5mm dust caps are the same, as the threads are the same. Likewise, 2.4mm & 1.85mm dust caps are the same, the threads being the same. Some people use opens for calibration purposes at low frequencies, but these opens are not VNA rated, we don't measure fringing capacitance etc.

Couplers
We offer SMA, 2.92mm, & 4.3/10 Directional couplers, useful in tapping off a portion of a signal, often for monitoring purposes. The 4.3/10 Couplers are low PIM.

Impedance Matching Pads
These impedance matching pads are resistive networks that can be used to match 2 devices with different nominal impedances. The resistive network used in these impedance matching pads has a 5.7db theoritical insertion loss; true loss is 5.7db plus the normal other losses. common use is to connect 50 ohm sma's to 75 ohm f's. There are also 75 ohm versons of N's, BNC's, & SMA's.

Power Dividers
We currently offer coaxial resistive power dividers (aka power splitters), which are inherently broadband and have excellent low frequency response (0!) albeit with poor isolation; and also Wilkinson Power dividers, aka Wilkinson Splitters. We have as connector options SMA, N, 1.95mm, & 2.92mm. Our power dividers cover DC-70Ghz. While most of our power dividers are 2-ways, we also have 3, 4, & 8 way dividers. The resistive power splitters are implemented with tiny resistors. Wilkinson splitters can be microstrip or stripline. RF Power Dividers are often lumped element, Microwave Power Dividers are often microstrip.

Hybrids
Hybrids, or Hybrid couplers, split signals while maintaining a fixed phase offset. 90 degree hybrids are common in balanced amplifier configurations.

Attenuators
We feature over 20,000 Microwave & RF Attenuators from 0-67GHz in stock. 1.85mm 67ghz attenuators. SMA attenuators to 3ghz, SMA Attenuators to 6ghz, 18ghz, & 27ghz; Type N attenuators to 6 ghz, 50 watt 3ghz Type N Attenuators, 500 watt 8.5ghz attenuators. Rotary, Variable, & Switch attenuators to 40Ghz. 2.4mm 50ghz attenuators.

Bias T's
Centric RF offers Coaxial Bias T's so that a DC voltage can be applied to the rf signal path. These Bias Tee's (aka bias t) currently are offered with sma and 2.92mm connectors. Bias T's are implemented by attaching a broadband inductor to the circuit trace, with the power rating of the bias tee being determined by the size of the inductor.

Cable Assemblies
We offer a variety of cables covering DC to 110Ghz. Cable assemblies from 0-6Ghz we usually build in our Quick Turn Cable Assembly Shop, delivery is 1-2 days. We also offer some Low Loss Phase Stable from our quick turn shop; but some of the precision cables can take longer.
