Functional Diagram
General Description
The HMC603MS10 & HMC603MS10E are general purpose broadband 5-bit positive control GaAs IC digital attenuators in 10 lead MSOP surface mount plastic packages. Covering 0.7 to 3.8 GHz, the insertion loss is less than 2.0 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4 and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ± 0.15 dB typical with an IIP3 of +50 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state at less than 1.0 uA each. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required.

Application Circuit
Note: DC Blocking Capacitors C1 & C2 are required on RF1 & RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest customer specifi c frequency to pass with minimal loss. R1= 5K Ohm is required to supply voltage to the circuit through either Pin 6 or Pin 10.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads 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.
