Technical Description
The CX42053 consists of two identical channels, A and B, that
were specifically designed for the purpose of diversity in base
station applications.
Each channel consists of a single-ended LNA and a double-
balanced differential mxer. The LNAs share a common CMOS-
compatible attenuator control switch, which bypasses the LNA,
providing 20 dB of attenuation.
Each channel shares two independent LO signals, LO1 and
LO2, that are selected using a common CMOS-compatible
control signal. With this ability, the device can be used in
applications where frequency hopping is required.
The LNAs and mxers are independently biased. This allows
design flexibility with power management functions in base
station receivers.
Electrical and Mechanical Specifications
The signal pin assignments and functions are described in
Table 1. The absolute maximumratings of the CX42053 are
provided in Table 2. The recommended operating conditions are
specified in Table 3 and electrical specifications are provided in
Table 4. Table 5 provides additional electrical specifications for
full channel performance.
Typical performance characteristics of the CX42053 are
illustrated in Figures 3 through 9.
