Electrical Speci cations,

Typical Applications

The HMC290 & HMC290E are broadband 2 - bit

positive control GaAs IC digital attenuators in 6 lead

SOT26 surface mount plastic packages. Covering 0.7

to 4 GHz, the insertion loss is typically less than 0.7

dB. The attenuator bit values are 2 (LSB) and 4 dB for

a total attenuation of 6 dB. Accuracy is excellent at ±

0.2 dB typical with an IIP3 of up to +52 dBm. Two bit

control voltage inputs, toggled between 0 and +3 to

+5 volts, are used to select each attenuation state at

less than 50 uA each. A single Vdd bias of +3 to +5

volts applied through an external 5K Ohm resistor is

required. Occupying less than 9 mm, this is the small-

est 2 - bit digital attenuator available.

The HMC290 / HMC290E is ideal for:

• Cellular

• PCS, ISM, MMDS

• WLL Handset & BaseStation

Application Circuit

DC blocking capacitors C1 & C2 are required on RF1 &

RF2. Choose C1 = C2 = 100 ~ 300 pF to allow lowest

customer speci c frequency to pass with minimal loss.

R1 = 5K Ohm is required to supply voltage to the circuit

through either PIN 3 or PIN 1.

The circuit board used in the  nal 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.
