TTL-Controlled Bi-Phase Modulators
Fairview Microwave Inc. 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. Useful applications include military and commercial communications systems, microwave radio, radar, high-data-rate test and measurement, serial data transmission and wireless base station infrastructure.

Direct Reading Digital Display Waveguide Attenuator
Millimeter Wave Products (Mi-Wave) has released a new 515 series, highly accurate direct reading digital waveguide attenuator. Based on the industry standard 510 series direct reading attenuator, the new model 515 boasts resolutions down to 0.01 dB, 0 to 20 dB and 0.1 dB from 20 to 60 dB. Attenuation accuracies rival vector network analyzer performance. Waveguide bands WR-112 to WR-03 are available. The attenuator operates from a standard USB C that charges the internal battery, up to 40 hours of usage and powers the unit.
