A fully integrated, Silicon Bipolar RF Power Amplifier for GSM, operating from a single 3 Volt Supply Voltage

In this article the design is discussed of a commercial available, 3.5Watt, very small size, RF power amplifier for GSM mobile phones. This amplifier is low cost, and does not require external components. This amplifier is realized with silicon MMIC in a new RF-IC process. on a ceramic substrate. It operates from a single 3Volt-power supply.
