Functional Diagram
General Description
the HMC802LP3e 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 less than 3 dB typical and attenuation accuracy is excellent at ±0.6 dB typical. the attenuator also features a high IIP3 of +55 dBm. one ttL/CMos control input is used to select the attenuation state and a single Vdd bias of +5V is required.

Pin Descriptions
Pin number 1 Function Vdd Description supply Voltage. these pins and the exposed ground paddle must be connected to rF/DC ground. these pins are DC coupled and matched to 50 ohms. Blocking capacitors are required. select value based on lowest frequency of operation. external capacitor to ground is required. select value for lowest frequency of operation. Place capacitor as close to pins as possible. the pins are not connected internally; however, all data shown herein was measured with these pins connected to rF/DC ground externally.

the circuit board used in the application should use rF circuit design techniques. signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. the evaluation circuit board shown is available from Hittite upon request.
