RF and microwave digital attenuator for military and commercial UHF applications introduced by Comtech PST

MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model LA01-001 digital attenuator for RF and microwave military or commercial applications in UHF band.

The design operates over the 400 to 500 MHz frequency range, and provides 0 to 60 dB of range for accuracy when changing attenuator steps.

Switching speed is fast when attenuation needs to be changed. Other RF and microwave frequencies, attenuation ranges, and performance characteristics are possible for other applications.

Features include TTL-controlled attenuation level; 4 bit attenuation control; 60 dB attenuation range; amplitude/phase matched state to state; attenuation accuracy; fast switching speed; +5-volt DC and -15-volt DC input.

The attenuator UHF applications has a frequency range of 400 to 500 MHz; maximum input power of 20 dBm; voltage standing wave ratio (VSWR) of 1.4:1 max, any state; insertion loss of 1.4 dB max; attenuation range if 0 to 60 dB, 6 dB steps; attenuator accuracy (to 36 dB) of ±0.25 dB max switching speed of 1 microsecond max; and impedance if 50 ohms.
