General Description
Pin Configuration
The TQM8M9077 is a digitally controlled variable gain
amplifier (DVGA) with a broadband frequency range of 50
to 4000 MHz. The DVGA features high linearity and low
noise while providing digital variable gain with a 31.5 dB
of range in 0.5 dB steps through a 6-bit serial mode control
interface. This combination of performance parameters
makes the DVGA ideal for receiver applications requiring
gain control with high IIP3.
The TQM8M9077 integrates a high performance digital
step attenuator and a high linearity, broadband gain block.
Both stages are internally matched to 50 Ohms and do not
require any external matching components. A serial output
port enables cascading with other serial controlled devices.
The TQM8M9077 is packaged in a RoHS-compliant,
compact 5x5 mm surface-mount leadless package.
Superior thermal design allows the product to have a
minimum MTTF rating of 1000 years at a mounting
temperature of +85º C.

Serial Control Interface
The TQM8M9077 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 SERIN) SPITM input compatible. At power up, the
serial control interface resets the DSA to the minimum gain state. The 6-bit SERIN word is loaded into the register on rising
edge of the CLK, MSB first. When LE is high, CLK is disabled.

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 0.25mm (0.10”).
4. Ensure good package backside paddle solder attach for reliable operation and best electrical performance.
5. Place mounting screws near the part to fasten a back side heat sink.
6. Do not apply solder mask to the back side of the PC board in the heat sink contact region.
7. Ensure that the backside via region makes good physical contact with the heat sink.
