Analog Devices extends its portfolio of RFICs with an analog-control variable-gain amplifier (VGA) that offers high linearity over a broad frequency range for wireless infrastructure applications, such as cellular basestation radio transceivers. The AD8368 is optimized to maintain dynamic range of basestation radio transceivers, ensuring that both weak and strong incoming call signals are handled and maintained. In addition, the AD8368 reduces the number of external components required by integrating an rms power detector on-chip, which enables a complete AGC loop within a 4 × 4 mm IC package. The AD8368 is capable of sustaining linearity of OIP3 of 34 dBm at 70 MHz at the highest IFs, allowing it to be used in all wireless standards, including 2G and 3G, as well as emerging broadband wireless standards such as 802.16 (WiMAX).
