PCF5079 is a dual-band power amplifier controller produced by Philips Semiconductors. It is suitable for GSM, PCN and DCS networks.
The PCF5079 is an integrated CMOS device designed to build a Power Amplifier (PA) control loop for cellular systems. It integrates an amplifier for detected RF voltage from the sensor, an integrator, and an active filter, requiring only a small number of passive components.
Key features include compatibility with baseband interface families like PCF5073x, two power sensor inputs with temperature compensation, and PA protection against mismatching. The device supports dual output with an internal switch and offers different transfer functions adaptable to various silicon PAs.
| Supply Voltage (Vop) | 2.5 to 5.0 V |
|---|---|
| Total Supply Current (Ipp_tot) | 10 mA |
| Ambient Temperature Range | -40 to +85 °C |
| Sensor Signal Input Range | -20 to +15 dBm |
The device supports Global System for Mobile communication (GSM), Personal Communications Network (PCN) systems, and DCS.
The PCF5079T uses a TSSOP10 plastic thin shrink small outline package with 10 leads.
