... Electrostatic sensitive device. Observe precautions for handling. Description The U7004B is a monolithic SiGe transmit/receive front end IC with power amplifier, 50- W internal matching, low-noise amplifier and T/R switch driver 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 V Figure 1 ...
