General Description
TriQuint’s TGA2237-SM is a wideband distributed
amplifier fabricated on TriQuint’s production 0.25um GaN
on SiC process. The TGA2237-SM operates from 0.03 –
2.5GHz and provides greater than 10W of saturated
output power with greater than 13dB of large signal gain
and greater than 50% power-added efficiency.
The TGA2237-SM is available in a low-cost, surface
mount 32 lead 5x5 AIN QFN. It is ideally suited to
support both radar and communication applications
across defense and commercial markets as well as
electronic warfare. The TGA2237-SM is fully matched to
50Ω at both RF ports allowing for simple system
integration. DC blocks are required on both RF ports and
the drain voltage must be injected through an off chip
bias-tee on the RF output port.
Lead-free and RoHS compliant.
Evaluation boards are available upon request.

TGA2237-SM
0.03 – 2.5GHz 10W GaN Power Amplifier
Application Circuit (Coaxial input DC block and coaxial output bias tee)
Notes:
1.
2.
Coaxial input DC block (C3) is used for input port (RF In.)
External wide bandwidth Bias-Tee is used for output port (RF Out). VD is applied through the output Bias-
Tee.
Bias-up Procedure
1. Set ID limit to 700mA, IG limit to 7mA
2. Set VG to -5.0V
3. Set VD +32V
4. Adjust VG more positive until IDQ = 360mA (VG ~ -2.6V
Typical)
5. Apply RF signal *
Bias-down Procedure
1. Turn off RF signal
2. Reduce VG to -5.0V. Ensure IDQ ~ 0mA
3. Set VD to 0V
4. Turn off VD supply
5. Turn off VG supply
(*) PIN is limited to 26dBm for frequency < 0.6GHz due to high gate current.
