General Description
Pin Configuration
The TQM8M9074 is a high dynamic range analog
controlled variable gain amplifier (VGA) which operates
from 0.7 to 2.8 GHz. The VGA is able to achieve high
performance with +43 dBm OIP3 and +27.5 dBm P1dB
over a wide gain variation range while only consuming 225
mA current.
The TQM8M9074 integrates a high linearity, low noise
amplifier for the first stage, followed by a broadband
voltage variable attenuator, and then with a high
performance ½W P1dB amplifier. The input and output of
the various individual stages are accessible with external
pins to allow for optimization of performance at any sub-
band across the VGA’s 0.7 to 2.8 GHz operating frequency
range. The TQM8M9074 is packaged in a RoHS-
compliant, compact 5x5mm 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.
The TQM8M9074 is targeted for use in wireless
infrastructure where high linearity, medium power, and
high efficiency are required.

Notes:
1. The gain variation range is measured as the difference in gain with Vctrl = 5 V and Vctrl = 0 V.
2. OIP3 measured with two tones at an output power of +11 dBm / tone separated by 1 MHz. The suppression on the largest IM3 product
is used to calculate the OIP3 using a 2:1 rule.
3. 3GPP WCDMA, 1±64DPCH, 3.84 MHz BW, PAR=10.2 dB at 0.01% Probability, single carrier.
4. Amp1 current (pin 3) is typically 75 mA.
5. Amp2 current (pin 15) is typically 150 mA.
6. VVA typical current is 3.6 mA for min attenuation and 1.6 mA for max attenuation.
