HMC973LP3E

GaAs MMIC VOLTAGE-VARIABLE

ATTENUATOR, 0.5 - 6.0 GHz

v00.0910

General Description

Features

Functional Diagram

excellent Linearity: +35 dBm Input IP3

Wide Attenuation range: 26 dB

single Positive Voltage Control: 0 to +5V

Absorptive topology

16 Lead 3x3mm sMt Package: 9mm²

Typical Applications

the HMC973LP3e is ideal for:

• Point-to-Point radio

• Cellular/3G & WiMAX/4G Infrastructure

• test Instrumentation

• Microwave sensors

• Military, eCM & radar

the HMC973LP3e is an absorptive Voltage Variable

Attenuator (VVA) which operates from 0.5 to 6 GHz

and is ideal in designs where an analog DC control

signal must be used to control rF signal levels over

a 26 dB amplitude range. It features a shunt-type

attenuator controlled by an analog voltage, Vctrl. un-

like other GaAs Fet based VVA’s the HMC973LP3e

exhibits excellent linearity of +35 dBm input IP3,

throughout it’s control range. the HMC973LP3e

is an unidirectional device with optimum linearity

performance achieved when the rF input signal is

applied to the rFIn package lead. the HMC973LP3e

is housed in a roHs compliant 3x3 mm QFn leadless

package.
