PASTERNACK Line of bi-phase modulators includes a comprehensive selection of nine different models covering broad octave frequency bands ranging from 0.5 to 40GHz. Bi-phase modulators take a TTL level digital bits stream that is encoded onto the RF carrier using 2 Phase Shift Keying (2PSK) modulation, where the 2 phases are separated by 180 degrees. This performance is suitable in communications systems, microwave radio, radar, high-data-rate test & measurement, serial data transmission, base station infrastructure and other industrial and military applications. The line of 0° to 180° devices deliver TTL command control, low insertion loss of 2.5dB typ, 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 the input and output RF ports are bi-directional. Devices operate across a wide temperature range from -40°C 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.
