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 (SPITM).
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.

1.4 – 2.7 GHz 1/4 W Digital Variable Amplifier
Detailed Device Description
The TQM879006A 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 a low noise amplifier gain block, a digital step
attenuator (DSA), along with a high linearity ¼W amplifier as shown in the functional diagram below. 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.

1.4 – 2.7 GHz 1/4 W Digital Variable Amplifier
Device Detailed Description
AMP1
AMP1 is a wide band low noise amplifier gain block in DVGA module. The amplifier provides 19 dB gain, 1.3 dB noise
figure, +36 dBm OIP3 at 2.0 GHz while only drawing 85 mA current. External DC blocks and biasing is not required. AMP1
is DC blocked internally and is connected internally to three bypass capacitors (22 pF, 100 pF, 0.01 uF) followed by 22 nH
inductor inside the module as shown in the figure below.

DSA (Digital Step Attenuator)
DVGA has a serial digital step attenuator that is controlled with 6-bit serial periphery interface (SPITM) and has 0.5 dB step
size with 31.5 dB attenuation range. This 50-ohm RF DSA maintains high attenuation accuracy over frequency and
temperature. “000000” represents maximum attenuation state. External bypass capacitors are needed to compensate the
inductance effect associated with long transmission lines on the evaluation board.
AMP2
AMP2 is high linearity ¼-W amplifier in DVGA module. The amplifier provides 14.4 dB gain, +24.5 dBm P1dB, +43 dBm
OIP3 at 2.0 GHz while only drawing 87 mA current. The amplifier is optimized over 1.4 – 2.7 GHz bandwidth using internal
matching components. AMP2 is DC blocked internally and is connected internally to two bypass capacitors (22 pF, 0.01
uF) followed by an 18 nH inductor inside the module as shown in the figure below. External DC blocks and biasing is not

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.
