Model LA01-001 is a new 60 dB digital attenuator for applications in UHF band. The design operates over the 400 to 500 MHz frequency range intended for use in military or commercial applications. The attenuator provides 0 to 60 dB of range. The accuracy achieved is exceptional when changing attenuator steps. Switching speed is very fast when attenuation needs to be changed. Other features include TTL controlled attenuation level, 4 bit attenuation control, amplitude/phase matched state to state, and +5 VDC and -15 VDC input.
