USB Style  RF/Microwave Components

Planar Monolithics Industries (PMI) has developed a family of USB controlled RF and microwave components including amplifiers, switches and attenuators. Two amplifiers are available operating from 0.05 to 18 GHz and 0.05 to 40 GHz with 12 dB gain, ±2.5 dB gain flatness, 4.5 dB typical noise figure to 20 GHz, OP1dB of +10 dBm typical and VSWR of 2.3:1. Two absorptive switch models are available operating from 0.5 to 18 GHz and 0.5 to 40 GHz with insertion loss of 5 dB (18 GHz model) and 6 dB (40 GHz model), 60 dB isolation and operating input power of 20 dBm. Two attenuator models are available operating from 0.1 to 18 GHz and 0.1 to 40 GHz with 30 dB attenuation range in 1 dB steps,±2.5 dB attenuation accuracy, 5 dB insertion loss to 20 GHz and VSWR of 2.5:1.

All components are controlled and powered via USB 2.0 interface using a custom PMI graphic user interface for control using a PC. Other models and custom components are also available.
