Fairview Microwave has just 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 two 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 zero 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 0.5W. 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 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.

Fairview Microwave’s new bi-phase modulators are in-stock and available for immediate shipping with no minimum order quantity (MOQ) required.
