Typical Application Circuit
General Description
The MAX2687/MAX2689/MAX2694 low-noise amplifiers
(LNAs) are designed for GPS L1, Galileo, and GLONASS
applications. Designed in Maxim’s advanced SiGe pro-
cess, the devices achieve high gain and low noise figure
while maximizing the input-referred 1dB compression
point and the 3rd-order intercept point. The MAX2687/
MAX2689/MAX2694 provide high gains of 12dB, 15dB,
and 18dB, respectively. Each is optimized for high
linearity.
The devices operate from a +1.6V to +3.6V single sup-
ply. The optional shutdown feature in the devices reduc-
es the supply current to less than 10FA. The devices
are available in a very small, lead-free, RoHS-compliant,
0.86mm x 0.86mm x 0.65mm wafer-level package (WLP).

Bump Description
Bump Configuration
Detailed Description
The MAX2687/MAX2689/MAX2694 are LNAs designed
for GPS L1, Galileo, and GLONASS 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
Application Circuit shows the recommended input-
matching network. These values are optimized for the
best simultaneous gain, noise figure, and return loss
performance. The value of the input coupling capacitor
affects IIP3. A smaller coupling capacitor results in lower
IIP3. The devices integrate an on-chip output matching
to 50I at the output, eliminating the need for external
matching components. Tables 1 and 2 list typical device
S parameters and Kf values. Typical noise parameters
are shown in Tables 3 and 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 VCC is applied, due to the on-chip
pullup resistor to VCC 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., 25kI, in order not to load the
RF output signal during active operation.

A2 RFOUT
(SHDN)
RF Output/SHDN Input. RFOUT is internally matched to 50I and pulled up to VCC through a 1MI
resistor. SHDN is shared with the RFOUT bump. The devices are in active mode by default once
VCC is applied. RFOUT(SHDN) can be pulled to a DC low through a 25kI resistor to shut down
the IC.
B1 RFIN RF Input. Requires a DC-blocking capacitor and external matching components.
B2 GND Ground. Connect to the PCB ground plane.

Applications Information
A properly designed PCB is essential to any RF micro-
wave circuit. Use controlled-impedance lines on all
high-frequency inputs and outputs. Bypass VCC with
decoupling capacitors located close to the device. For
long VCC lines, it may be necessary to add decoupling
capacitors. Locate these additional capacitors further
away from the device package. Proper grounding of
the GND bump is essential. If the PCB uses a topside
RF ground, connect it directly to the GND bump. For a
board where the ground is not on the component layer,
connect the GND bump to the board with multiple vias
close to the package.
