    Qorvo's TGA1135B-SCC is a balanced two stage HPA MMIC design using Qorvo's proven 0.25 um Power pHEMT process. The TGA1135B-SCC is designed to support a variety of millimeter wave applications including point-to-point digital radio and LMDS / LMCS.

    The balanced configuration two stage design consists of a pair of 600 um input devices driving a 4 x 600 um output stage. Power combining is achieved with on-chip Lange couplers. The TGA1135B-SCC provides 29 dBm nominal output power at 1dB compression across 18 - 27GHz. Typical small signal gain is 14 dB across the band. Input and output return loss is typically -15dB.

    An on-chip power detector and reference diode may be used for power monitoring / control and bias control loops. The TGA1135B-SCC requires minimum off-chip components. Each device is 100% DC and RF tested on-wafer to ensure performance compliance. The device is lead-free and ROHS compliant and available in chip form.
