Functional Block Diagram

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

int

egration 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).

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.

The TQM8

79006A

is pin compatible with the

TQM8

29007 (0.6-1

GHz, 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.

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 (D

SA), 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.

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.

Device Detailed Description

AMP

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 i

PCB Mounting Pattern

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.
