The VM103D, is a wide band GaAs MMIC:
– 5-bit attenuator
– Digital control logic
The digital control logic allows for parallel data input, so attenuation value may be changed instantaneously. This broadband Attenuator has an LSB of 0.9dB, and controlled by 5 digital binary inputs, compatible with LVCMOS / TTL levels. This device uses a single -7.5V Bias supply voltage.
