The TGA2567-SM operates from 2 to 20 GHz and
typically provides 19 dBm of 1dB compressed output
power with 17 dB of small signal gain. Greater than 16
dB of adjustable gain can be achieved by varying VG2.
The Noise Figure is typically 2 dB at mid band
The TGA2567-SM is available in a low-cost, surface
mount 24 lead 4x4 AIN QFN package base with an Air
cavity LCP lid. TGA2567-SM is ideally suited to support
both commercial and defense related applications.
Lead-free and RoHS compliant.
Evaluation Boards are available upon request.

Application Circuit
Notes: To prevent damage to the device due to overshoot or oscillation issues, we recommend that current limits for all power
supplies are set properly for each power supply before applying the voltage. The following are recommended current limits for
each power supply:
Set 10 mA current limit to VG1 and VG2
Set 140 mA current limit to VD
Bias-up Procedure
Bias-down Procedure
1. Apply -1.5 V to VG1.
2. Apply +5 V to VD.
3. Apply +1.3 V to VG2.
4. Adjust VG1 until IDQ = 100 mA (VG1 ~ -0.7 V Typ.).
5. Turn On RF supply.
6. Adjust VG2 to obtain desired gain
1. Reduce VG2 to +1.3 V.
2. Turn off RF supply.
3. Reduce VG1 to -1.5 V. Ensure IDQ ~ 0 mA
4. Set VG2 to 0 V.
5. Set VD to 0 V.
6. Set VG1 to 0 V.

Mechanical Information
All dimensions are in inches. Unless specified otherwise, tolerances: ± 0.127 in.
Marking: Part number – 2567
Year/Month code – YYMM
Batch ID – MXXX
Package Materials:
Base Aluminum Nitride (AIN)
Lid
Liquid Crystal Polymer (LCP)
Part is EPOXY Sealed
Land Pads are Gold Plated
PCB Mounting Pattern
The pad pattern shown above has been developed and tested for optimized assembly at TriQuint. The PCB land
pattern has been developed to accommodate lead and package tolerances. Since surface mount processes vary from
company to company, careful process development is recommended.
Ground / thermal vias are critical for the proper performance of this device. Vias should use a 0.008 in. diameter drill,
and they are solid filled, copper plated shut.
