CentricRF

CentricRF

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.

Resistors

Vishay Intertechnology, Inc.

Vishay Intertechnology, Inc.

A passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

SSPAs / LNAs / Broadband

Nanowave Technologies Inc.

Nanowave Technologies Inc.

SSPAs based on the latest Galium Nitride (GaN) technology offer the best combination of high peak powers, high reliability, high efficiency, and soft degradation. High efficiency and high power are hallmarks of GaN technology, enabling SSPAs to challenge traditional tube-based amplifiers across the design spectrum. In addition the long lifetime from these devices, combined with the gradual degradation should individual devices fail, provide unparalleled service lifetime. Techniques such as bias modulation and linearization provide even better prime-power efficiency while still meeting the demanding requirements of pulsed or CW applications.

Low Noise Pre-Amplifiers

Praxsym

Praxsym

Low Noise Pre-Amplifier and companion external low noise amplifier (LNA) are used to amplify low level microwave signals. The Pre-Amplifier contains an AC/DC power supply, internal low noise amplifier, and a bias tee to source a DC bias voltage on the RF input connector.To overcome cable loss between the test antenna and the Pre-Amplifier assembly, a remote low noise amplifier (LNA) is mounted directly onto the 10 GHz antenna. A bias tee inside the Pre-Amplifier chassis powers the remote LNA through the coax cable interconnecting the pre-amplifier and the 10 GHz test antenna.

Broadband Detectors

Pacific Millimeter Products

These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.
