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.
