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 inser-
tion 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 specific frequency to pass with minimal loss.
R1= 5K Ohm is required to supply voltage to the circuit
through either Pin 6 or Pin 10.

* R2 - R6= 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
List of Materials for Evaluation PCB 112747 [1]
The circuit board used in the final application should
useRFcircuitdesigntechniques. Signallinesshould
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.
