RFMW announces design and sales support for a high-linearity, two-stage power amplifier in a low-cost surface-mount package. The Qorvo QPA9903, with on-chip bias control circuit, is suitable for small cell base station applications over the 1805 – 1880 MHz frequency range (Band 3). Providing 32 dB gain and 36 dBm P3dB, the QPA9903 achieves −50 dBc, DPD corrected ACPR at +28 dBm output power. Internally I/O matched to 50 ohms and available in a 5 x 5 mm surface mount package, this device also serves m-MIMO and DAS systems.
RFMW announces availability of a broad-band gain block from Microwave Technology (MwT). The MMA-062020 GaAs MMIC gain block provides nearly 20 dBm of saturated output power over its full 6 to 22 GHz frequency range. Optimally designed for broadband applications requiring flat gain with excellent input and output port matches, the MMA-062020 provides 14 dB of gain with typical gain flatness of +/- 0.8 dB. P1dB output power measures >18 dBm with OIP3 of 28 dBm. Operating from a 5V drain-supply, this general purpose amplifier is offered as a 0.92 x 0.92 mm DIE.
RFMW announces design and sales support for a differential output gain block. Qorvo’s QPA9154 is input matched to 50 Ω and offers a 100 Ω differential-output to directly interface with a transceiver ADC thereby eliminating the need for a discrete balun. Ideal for final gain stages in 2.3-3.8 GHz, 5G m-MIMO base stations, the QPA9154 delivers 19 dB of small signal gain and 35 dBm OIP3. The amplifier features a shut-down function and gain flatness of 0.5 dB over any 400 MHz bandwidth. Housed in a compact 2 x 2 mm SMT package.
RFMW announces availability of a portfolio of broad-band SMD filters from Knowles (DLI). The portfolio is comprised of ceramic substrate filters using patented materials which exhibit excellent temperature stability and high K factors. Combined, these characteristics enable small size with high performance. Supporting general purpose and T&M applications, popular bandwidths include 2 to 4 GHz, 4 to 8 GHz, 8 to 12GHz and 12 to 18 GHz. For example, the B096QC2S, 8 to 12 GHz filter measures just 10.1mm x 4.6mm x 2.5mm while offering 2.5 dB typical insertion loss with 50 dB out-of-band rejection. Catalog devices come complete with…
