Detailed Description
Signal Paths and Operation Modes
The MAX2351/MAX2354/MAX2358/MAX2359/MAX2530/
MAX2531/MAX2537/MAX2538 have multiple RF signal
paths. The cellular signal path has five modes of opera-
tion using a 4-gain-mode LNA and a 3-gain-mode mixer.
Similarly, the PCS signal path has four modes of opera-
tion made up of a 2-gain-mode LNA and a 3-gain-mode
mixer. The cellular and PCS mixer’s IF output can be
routed to either the IF0 or IF1 port. The GPS signal path
consists of a single-mode GPS, LNA, and mixer, which
has a dedicated IF output port. Tables 1 and 2 summa-
rize the modes of operation.
Low-Noise Amplifiers
The MAX2351/MAX2358/MAX2530/MAX2531/MAX2538
incorporate three LNA signal paths for the cellular,
PCS, and GPS bands. Using Maxim’s latest advanced
BiCMOS SiGe process, these LNAs deliver 1dB noise
figure for cellular, PCS, and GPS bands. The cellular
band LNAs have four modes of operation: high gain/
high linearity (HGHL), high gain/low linearity (HGLL),
midgain (MG), and low gain (LG). The PCS band LNAs
have two modes of operation: high gain/high linearity
and low gain. The GPS LNA has only one mode.
The BAND input selects the frequency band. The G1,
G2, and MODE pins are logic inputs that control the
LNA modes (see Table 2). Use HGHL mode when high
