T7026

Features Single 3-V Supply Voltage High-power-added Efficient Power Amplifier (Pout Typically 28 dBm) Ramp-controlled Output Power Low-noise Preamplifier (NF Typically 2.1 dB) Biasing for External PIN Diode T/R Switch Current-saving Standby Mode Few External Components Package: QFN20 ISM 2.4 GHz Front End IC T7026 1. Description The T7026 is a monolithic SiGe transmit/receive front-end IC with power amplifier, low-noise amplifier and T/R switch driver. It is especially designed for operation in TDMA systems like DECT, IEEE 802.11 FHSS WLAN, home RF and ISM proprietary radios. Due to the ramp-control feature and a very low quiescent current, an external switch transistor for VS is not required. Electrostatic sensitive device. Observe precautions for handling. www.DataSheet4U.com Figure 1-1.
