SiGe SE2566UDesigned for WiFi applications, SiGe Semiconductor's SE2566U RF front-end solution incorporates 2 fully-matched power amplifiers on a single die. The 3-mm × 3-mm device integrates harmonic filters, input and output matching circuitry and power detectors for each transmit stream. The product includes an integrated receive path situated between the 2 transmit paths to offer layout flexibility for 2-transmit by 2-receive (2×2) or 2×3 architectures. The unit has harmonic contribution of -50 dBm/MHz and support for MIMO capability for 802.11n implementations. A temperature-compensated, load-insensitive transmit power detector offering 20 dB of dynamic range is included. A reference voltage generator allows 1.8-V CMOS digital enable control directly from the baseband, and eliminates the need for analog bias controls while drawing <1 µA. Pricing is $0.60 in 10,000 quantities.
