DECT SiGe Front End IC with High PAE U7006B
Description
The U7006B is a monolithic SiGe transmit/receive front end IC with power amplifier, 50-W internal matching, low-noise amplifier and T/R switch driver. It is especially designed for operation in TDMA systems like DECT. Due to the ramp-control feature and a very low quiescent current, an external switch transistor for VS is not required. Figure 1.
