Product Overview
The TQM879008 is a digital variable gain amplifier (DVGA)
featuring high linearity over the entire gain control range.
This amplifier module integrates two gain blocks, a digital-
step attenuator (DSA), and a high linearity ½ W amplifier.
The module has the added feature of integrating all
matching components, bias chokes and blocking
capacitors. The internal 6-bit DSA provides a 31.5 dB gain
control range in 0.5 dB steps, and is controlled with a serial
periphery interface (SPITM).
28-pin 6x6 mm leadless SMT Package
Key Features
• 1.4-2.7 GHz Frequency Range
• 41.1 dB Maximum Gain at 2.5 GHz
• 31.5 dB Gain Range in 0.5 dB Steps
• +47.5 dBm Output IP3
The TQM879008 features variable gain from 10 dB to
41.1dB at 2.5 GHz, +47.5 dBm output IP3, and +27.3 dBm
P1dB. The module operates from a single +5V supply and
is available in a compact 28-pin 6x6 mm leadless SMT
package.
• +27.3 dBm Output P1dB
• Fully Internally Matched Module
• Integrated Blocking Capacitors, Bias Inductors
• 3-wire SPI Control Programming
The TQM879008 is pin compatible with the TQM829007
(0.7-1.0GHz, 0.25W DVGA) and TQM879006 (1.4-2.7GHz,
0.25W 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.

Serial Control Interface
The TQM879008 has a CMOS SPITM input compatible serial interface. This serial control interface converts the serial
data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPITM input compatible. At power up, the
serial control interface resets the DSA to the minimum gain state. The 6-bit SID (Serial Input Data) word is loaded into the
register on rising edge of the CLK, MSB first. When LE is high, CLK is internally disabled.

Detailed Device Description
The TQM879008 is a 50 Ω internally matched digital variable gain amplifier (DVGA) featuring high linearity over the entire
gain control range. The amplifier module features the integration of two gain block, a digital-step attenuator (DSA), along
with a high linearity ½ W amplifier. The module is unconditionally stable. Internal blocking capacitors and bias structures
keep external parts count to a minimum. The DVGA has an operational frequency range from 1.4-2.7 GHz.

Notes:
1. All dimensions are in millimeters. Angles are in degrees.
2. Use 1 oz. copper minimum for top and bottom layer metal.
3. Vias are required under the backside paddle of this device for proper RF/DC grounding and thermal dissipation. We recommend
a 0.35mm (#80/.0135") diameter bit for drilling via holes and a final plated thru diameter of 0.25 mm (0.10”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
