The HMC800LP3E is a broadband bidirectional 1-bit
GaAs IC digital attenuator in a low cost leadless
surface mount package. This single positive control
line digital attenuator utilizes off chip AC ground
capacitors for near DC operation, making it suitable
for a wide variety of RF and IF applications. Covering
DC to 10 GHz, the insertion loss is 2 dB typical and
attenuation accuracy is excellent at ±0.3 dB typical
step error. The attenuator also features a high Input
IP3 of +55 dBm. One TTL/CMOS control input is used
to select the attenuation state and a single Vdd bias of
+5V is required.
