Bi-phase modulators operating in bands from 0.5 to 40GHz

Bi-phase modulators take a TTL level digital bits stream that is encoded onto the RF carrier using two Phase Shift Keying (2PSK) modulation, where the two phases are separated by 180 degrees. This performance is desirable in communications systems, microwave radio, radar, high-data-rate test & measurement, serial data transmission, base station infrastructure and other industrial and military applications. 

Pasternack’s new line of zero to 180° bi-phase modulators offer impressive features that include TTL command control, low insertion loss of 2.5 dB typ, 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 the input and output RF ports are bi-directional. These bi-phase modulators operate across a wide temperature range from -40 to +85°C. 

The compact and rugged packages utilize solder pins for TTL, DC bias and ground, and field replaceable SMA or 2.92mm female connectors. All designs are highly reliable, meeting MIL-STD-202 environmental test conditions for humidity, shock, vibration, altitude and temperature cycle.

“These fully integrated bi-phase modulators offer desirable and accurate performance features for modulating a signal response over broad frequency bands. Production lead-times for these products are normally 22 to 24 weeks. Having a comprehensive selection readily available in stock is invaluable for designers who have an urgent need to validate prototype or proof-of-concept designs,” said Tim Galla, Product Line Manager at Pasternack.

Pasternack’s new bi-phase modulatorsare in stock and available for immediate shipping with no minimum order quantity (MOQ) required.
