RFMD RF3283
The RF3283 is a high-power, high-efficiency transmit module containing RFMD’s PowerStar™ integrated power control, integrated pHEMT front end antenna switch and harmonic filtering functionality. The device is self-contained with 50 Ω input and output terminals with no matching components required. The integrated power control function based on RFMD’s patented PowerStar™ control is incorporated, eliminating the need for directional couplers, detector diodes, power control ASIC’s, and other power control circuitry; this allows the module to be driven directly from the DAC output.| Part No. | RF3283 |
