Abstract :
A low cost integrated 2 GHz 500 mW amplifier for DECT and other applications is presented. The total efficiency is 35% with a 3.3 V supply voltage and 0 dBm input signal. The chip is based on the Siemens B6HF 26 GHz-f/sub T/-technology and is to our knowledge the first commercial 500 mW 2 GHz amplifier in bipolar technology. The device also features functions which are previously not available from PA ICs including power down, power selection and supply voltage compensation.
