Fairview Microwave Inc. has released a new line of bi-phase modulators covering broad octave frequency bands from 0.5 to 40 GHz. These models use TTL logic to phase modulate data onto an RF carrier signal using 2 phase shift keying (2PSK). Useful applications include military and commercial communications systems, microwave radio, radar, high-data-rate test & measurement, serial data transmission and wireless base station infrastructure.

Fairview Microwave’s new series of 0° to 180° bi-phase modulators includes nine models that offer impressive performance that includes low insertion loss of 2.5 dB typical, fast switching speed of 40 nsec typ, low VSWR of 1.8:1 typ and maximum peak RF input power of 0.5 watts. All designs require dual bias voltages, and input and output RF ports are bi-directional. These compact and rugged packages utilize solder pins for TTL control, DC bias and ground, and field replaceable SMA or 2.92mm female connectors They operate across a wide temperature range from -40°C to +85°C. All models are highly reliable, meeting MIL-STD-202 environmental test conditions for humidity, shock, vibration, altitude and temperature cycle.

“Not only does this line of bi-phase modulators deliver impressive performance features for modulating RF carrier signals over broad frequency bands, we’re also able to provide them with same-day shipping, avoiding the usual 22-24 week production lead-times of our competitors,” said Tim Galla, Product Line Manager.
