RMPA0965
Overview
The RMPA0965 power amplifier module (PAM) is designed for cellular band AMPS, CDMA and CDMA2000-1X applications. The 2 stage PAM is internally matched to 50Ω to minimize the use of external components and features a low-power mode to reduce standby current and DC power consumption during peak phone usage.
- Single positive-supply operation with low power and shutdown modes
- 40% CDMA efficiency at +28 dBm average output power
- 52% AMPS mode efficiency at +31 dBm output power
- Compact LCC package ( 3.0 x 3.0 x 1.0 mm)
- Internally matched to 50Ω and DC blocked RF input/ output
- Meets CDMA2000-1XRTT performance requirements Device Absolute Ratings1 Symbol Vcc1, Vcc2 Vref Vmode Pin TSTG Parameter Supply Voltages Reference Voltage Power Control Voltage RF Input Power Storage Temperature Value 5.0 2.6 to 3.5 3.5 +10 -55 to +150 Units V V V dBm °C Note: 1: No permanent damage with only one parameter set at extreme limit.
