Fixed Attenuator by API Technologies – Inmet | Visit website

The TCAF N05 Series are temperature variable chip attenuators that operate from DC to 12 GHz. The attenuators are designed to vary by -0.005 dB/dB/Degree C to compensate for temperature induced system gain variation without requiring a bias or control voltage. They offer the flattest broadband performance of their kind and will allow you to create automatic and passive link margin compensation on a variety of transmit- and receive-chain circuits. The attenuators are available in attenuation configurations ranging from 2 thru 6 dB and can handle up to 2 watts of power.

API Technologies Inmet PPT975-200LP

Termination by API Technologies – Inmet | Visit website

The PPT975-200LP from API Inmet is a low PIM, flanged termination that operates from DC to 4 GHz. It can handle up to 200 W of power, has a resistive tolerance of 5% and a VSWR of under 1.25:1. This termination has been designed to dissipate power in RF circuits when mounted to an appropriate heat sink. It has a PIM level of -120 dBc with two 43 dBm tones. This thin film termination has been developed on an aluminium nitride substrate, with an Alumina Ceramic cover and Nickel plated copper flanges.
