CX42053
700 – 1000 MHz High Dynamic Range, Diversity Receiver Front End
Skyworks’ CX42053 is an integrated, high-dynamc range, low-noise receiver down
converter for two-channel diversity systems. It includes a Low Noise Amplifier
(LNA) followed by a double-balanced active mxer. The CX42053 has dual Local
Oscillator (LO) inputs, selected using an external switch interface. The internal
attenuator is integrated with the LNA. The attenuator function is also controlled
using an externally controlled CMOS-compatible interface.
Figure 1 shows a functional block diagramfor the CX42053. The 24-pin Plastic
Quad Flat Pack (PQFP) device package and pinout are shown in Figure 2.
