Product Description Qorvo’s TGA3042-SM is a packaged high power MMIC amplifier fabricated on Qorvo’s production 0.15um GaN on SiC process (QGaN15). The TGA3042-SM operates from 7 – 10.5 GHz and typically provides 4.5 W saturated output power with power-added efficiency of 38.5% and large-signal gain of 23.5 dB. This combination of wideband performance provides the flexibility designers are looking for to improve system performance while reducing size and cost. The TGA3042-SM is matched to 50Ω with integrated DC blocking capacitors on both RF I/O ports simplifying system integration. The wideband performance makes it ideally suited in support of multiple radar and communication bands. Lead-free and RoHS compliant. Evaluation boards are available upon request.

Application Information
Bias Up Procedure 1. Set ID limit to 1000 mA, IG limit to 20 mA
2. Apply −5 V to VG
3. Apply +20 V to VD; ensure IDQ is approx. 0 mA
4. Adjust VG until IDQ = 200 mA (VG ~ −2.2 V Typ.).
5. Turn on RF supply
Bias Down Procedure 1. Turn off RF supply
2. Reduce VG to −5 V; ensure IDQ is approx. 0 mA
3. Set VD to 0 V
4. Turn off VD supply
5. Turn off VG supply

Evaluation Board (EVB) Layout
NOTES:
1. RF Layer is 8 mil thick Rogers Corp. RO4003C, r = 3.38. Both metal layers are 0.5 oz. copper.
2. TGA3042-SM can be biased from either the top side or the bottom side. Bypassing components are required for the side(s) being biased. Bypass components are required for the side not biased if using the EVB PCB layout in other applications. Do not include metal traces for applications using the EVB PCB layout if biasing and bypassing from one side only

Assembly Notes
Compatible with lead-free soldering processes with 260°C peak reflow temperature. This package is air-cavity and non-hermetic, and therefore cannot be subjected to aqueous washing. The use of no-clean solder to avoid washing after soldering is highly recommended. Contact plating: Ni-Au. Solder rework not recommended.
