Abstract
This paper presents an active BiCMOS vector modulator based RF weighting circuit suitable for WLAN diversity transceivers. It features a LNA, a SPI and 8-bit DACs for vector control and internal references. When mounted on a PCB, it delivers a maximum gain of 12 dB at 5.6 GHz. It draws a current of 17 mA from a 3.3 V supply. The whole design is free of bulky inductors thus requiring an area of only 1.3 mm2.
