Functional Diagram
HMC973LP3E
GaAs MMIC VOLTAGE-VARIABLE
ATTENUATOR, 0.5 - 6.0 GHz
Features
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
General Description
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.

Description
These pins and the exposed ground paddle must
be connected to RF/DC ground.
This pin is DC coupled and matched to 50 Ohms.
A blocking capacitor is required if RF line potential
is not equal to 0V.
Supply Voltage
The pins are not connected internally; however, all data
shown herein was measured with these pins connected to
RF/DC ground externally.
Interface Schematic
Control Voltage
This pin is DC coupled and matched to 50 Ohms.
A blocking capacitor is required if RF line potential
is not equal to 0V. The HMC973LP3E is a unidirectional
device with optimum linearity performance achieved with
RF input signal applied to RFIN package lead.
