Qorvo’s new QPA2935 is a 2-Watt S-Band MMIC power amplifier and QPA0506 is a 4-Watt C-Band MMIC power amplifier (PA). Both are footprint compatible with predecessor devices, TGA2597-SM and TGA2599-SM, enabling a simple drop-in replacement option to instantly improve system performance in power and efficiency. The devices offer flexible bias points, enabling customers the ability to increase RF power as well.

QPA2935

2 Watt S-Band GaN Driver Amplifier

Key Features:

  • Frequency Range: 2.7 – 3.5 GHz
  • PSAT : 33 dBm (PIN = 15 dBm)
  • PAE: > 52 % (PIN = 15 dBm)
  • Small Signal Gain: 28.4 dB
  • Bias: VD = 25 V, IDQ = 29 mA
  • Package Dimensions: 4.00 x 4.00 x 0.85 mm

Qorvo’s QPA2935 is a MMIC power amplifier fabricated using Qorvo’s QGaN25 0.25 um GaN on SiC production process. Covering 2.7 - 3.5 GHz, the QPA2935 typically provides 33 dBm of saturated output power and 18 dB of large-signal gain while achieving greater than 52 % power-added efficiency.

The QPA2935 can support a variety of operating conditions to best support system requirements. With good thermal properties, it can support a range of bias voltages. The QPA2935 is matched to 50 ohms with integrated DC blocking caps on both I/O ports.

The QPA2935 is packaged in a plastic overmolded 4×4 mm package. The QPA2935 is 100% DC and RF tested to ensure compliance to electrical specifications.

Lead free and RoHS compliant.

  • PAE (PIN = 18 dBm): 53 %
  • Small Signal Gain: 27.4 dB
  • Input Return Loss: 26 dB
  • Output Return Loss: 13 dB
  • Recommended Bias: VD = 25 V, IDQ = 37.5 mA
  • Package Size: 4.0 mm x 4.0 mm x 0.85 mm

Qorvo’s QPA0506 is a MMIC power amplifier fabricated using Qorvo’s QGaN25 0.25 um GaN on SiC production process. Covering 5 – 6 GHz, the QPA0506 typically provides 36 dBm of saturated output power and 18 dB of large-signal gain while achieving 53 % power added efficiency.

The QPA0506 can support a range of bias voltages to optimize power and PAE to system requirements. The QPA0506 is matched to 50 ohms with a DC blocked input and a DC grounded output.

The QPA0506 is packaged in a plastic overmolded 4×4 mm package. The QPA0506 is 100% DC and RF tested to ensure compliance to electrical specifications.

Lead free and RoHS compliant.
