... For even lower quiescent current, a dynamic bias control circuit can be used by varying the voltage on the Vcntl pin between 1.2V to 2.5V. Designed in a surface mount RF package, the ACPM- 7833 is cost and size competitive. The ACPM-7833 is another key component of the Avago Technologies CDMAdvantage RF chipset. ...

... RTT in the multi-carrier mode. This paper describes the CDMA2000 1X RTT approach and its performance with Avago Technologies 4x4 CDMA PAs, ACPM-7833. CDMA2000 1X RTT, being an extension of the IS-95 standard, has a chip rate of 1.2288Mchip/s. However, in 1xRTT, the reverse link transmits more than one code channel to accommodate the high data rates ...

... Higher peak to average power ratio requires a higher margin, both in higher power gain and in improved thermal stability for PA linearity to meet the minimum system specifications. The test results below for the ACPM-7833 show the compliance to the system linearity specifications with 4 channel configurations, representing a broad cross- section of CDMA2000 1X RTT environments. ...

... Using a fixed bias point on the PA is the traditional method, and it is the simplest. For example, the recommended value of the fixed control voltage on the Vcntl pin for the ACPM-7833 is 2.5V. The Vcntl pin on the PA is controlled by PA_ON pin of the baseband IC. When PA_ON is HIGH, the output RF signal of the PA is enabled, enabling the subscriber unit to transmit the required data ...
