EVALUATION KIT AVAILABLE MAX2687/MAX2689/MAX2694 GPS/GNSS Low-Noise Amplifiers 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 process, 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 supply. The optional shutdown feature in the devices reduces 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).

Requires a DC-blocking capacitor and external matching components. B2 GND Ground. Connect to the PCB ground plane. 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 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. 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 inputmatching network. These values are optimized for the best simultaneous gain, noise figure, and return loss performance. The value of the input coupling capacitor Maxim Integrated 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 logiclow 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.   7 MAX2687/MAX2689/MAX2694 GPS/GNSS Low-Noise Amplifiers Table 1.

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.
