FUNCTION
Supply Voltage. Bypass to ground with a 10pF capacitor as close as possible to the IC.
RF Output/ SHDN Input. RFOUT is internally matched to 50 I and pulled up to V CC through a 25k I
resistor. SHDN is shared with the RFOUT bump. The devices are in active mode by default once
V CC is applied. RFOUT( SHDN ) can be pulled to a DC low externally to shut down the IC.
RF Input. Requires a DC-blocking capacitor and external matching components.
Ground. Connect to the PCB ground plane.
Detailed Description
The MAX2692/MAX2695 are LNAs designed for WLAN/
WiMax applications. The devices feature an optional
power-shutdown control mode to eliminate the need for
an external supply switch. The devices achieve high
gain, low noise figure, and excellent linearity.
Input and Output Matching
The devices require an off-chip input matching. Only an
inductor in series with a DC-blocking capacitor is needed
to form the input matching circuit. The Typical Operating
Circuit shows the recommended input-matching network.
These values are optimized for the best simultaneous
gain, noise figure, and return loss performance. The
devices integrate an on-chip output matching to 50 I at
the output, eliminating the need for external matching
components. Table 1 and Table 2 list typical device S
parameters and K f values. Typical noise parameters are
shown in Table 3 and Table 4 .
Shutdown
The devices include an optional shutdown feature to turn
off the entire chip. The devices are placed in active mode
by default once V CC is applied, due to the on-chip pul-
lup resistor to V CC at the RFOUT bump (shared with the
SHDN input). To shut down the part, apply a logic-low
to the RFOUT bump through an external resistor with an
adequate value, e.g., 25k I , in order not to load the RF
output signal during active operation.
