TQM879006A

1.4 – 2.7 GHz 1/4 W Digital Variable Amplifier

General Description

The TQM879006A is a digital variable gain amplifier

(DVGA) featuring high linearity over the entire gain control

range. The amplifier module features the integration of a

low noise amplifier gain block, a digital-step attenuator

(DSA), along with a high linearity ¼W amplifier. The

module has the added features of integrating all matching

components with bias chokes and blocking capacitors. The

internal DSA offers 0.5 dB step, 6-bit, and 31.5 dB range

and is controlled with a serial periphery interface (SPI^TM).

28 Pin 6X6 mm leadless SMT Package

The TQM879006A features variable gain from 0 dB to 31.7

dB at 2 GHz, has +43 dBm Output IP3, and +24.5 dBm

P1dB. The amplifier also has a very low 1.5 dB Noise

Figure (at maximum gain) allowing it to be an ideal DVGA

for both receiver and transmitter applications. The amplifier

operates from a single +5V supply and is available in a

compact 28-pin 6x6 mm leadless SMT package.

Product Features

• 1.4-2.7 GHz Frequency Range

• 31.7 dB Maximum Gain at 2 GHz

• 31.5 dB Gain Range in 0.5 dB Steps

• +43 dBm Output IP3

• +24.5 dBm Output P1dB

• 1.5 dB Noise Figure at Max. Gain State

• Fully Internally Matched Module

• Integrated Blocking Capacitors, Bias Inductors

• 3-wire SPI Control Programming

The TQM879006A is pin compatible with the TQM829007

(0.6-1GHz, 0.25W DVGA) and TQM879008 (1.5-2.7 GHz,

0.5W DVGA). This allows one to size the right type of

device for specific system level requirements as well as

making the DVGA family ideal for applications where a

common PCB layout is used for different frequency bands.
