A new line of wideband, hybrid power amplifier modules (HPMs) from AR RF Microwave Instrumentation covers the 6- to 18-GHZ frequency range. These hybrid modules require only a single DC volt source and are 50-ohm “cascadable” building blocks with output powers up 37 dBm. The six new hybrid power modules have excellent typical gain flatness, excellent noise performance, and low … [Read more...]
