Application Circuit
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 3 or PIN 1.
HMC290 / 290E
2 dB LSB GaAs MMIC 2-BIT DIGITAL
ATTENUATOR, 0.7 - 4.0 GHz
v01.0605
The circuit board used in the final application should
use RF circuit design techniques.
Signal lines
should have 50 ohm impedance while the pack-
age 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 cir-
cuit board as shown is available from Hittite Micro-
wave Corporation upon request.

* R2 = R3 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
