The HMC960LP4E is suitable for:

• Baseband I/Q Transceivers

• Direct Conversion & Low IF Transceivers

• Diversity Receivers

• ADC Drivers

• Adaptive Gain Control

The HMC960LP4E is a digitally programmable dual

channel variable gain amplifier. It supports discrete

gain steps from 0 to 40 dB in precise 0.5 dB steps.

It features a glitch free architecture to provide

exceptionally smooth gain transitions. The device

has matched gain paths which provide excellent

quadrature balance over a wide signal bandwidth.

The HMC960LP4E provides an SPI programmable

input impedance of 100 Ω differential or 400 Ω

differential (default).

Externally controlled common mode output feature

enables the HMC960LP4E to provide a flexible output

interface to other parts in the signal path.

Gain can be controlled via either a parallel interface

(GC[6:0]) or via the read/write serial port (SPI).

Housed in a compact 4x4mm (LP4) SMT QFN

package, the HMC960LP4E requires minimal external

components and provides a low cost alternative to

more complicated switched amplifier architectures.
