New series of TTL-controlled bi-phase modulators

02-11-2020 | Fairview | Subs & Systems

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


The company’s new series of 0-degree to 180-degree bi-phase modulators comprises nine models that deliver impressive performance that incorporates low insertion loss of 2.5 dB typical, fast switching speed of 40nsec typ, low VSWR of 1.8:1 typ and maximum peak RF input power of 0.5W. All designs need dual bias voltages, and input and output RF ports are bi-directional. These compact and rugged packages use solder pins for TTL control, DC bias and ground, and field-replaceable SMA or 2.92mm female connectors They perform across a broad temperature range from -40C to +85C. All models are highly reliable, meeting MIL-STD-202 environmental test conditions for humidity, vibration, shock, 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, but 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.
