MAX2692/MAX2695

WLAN/WiMAX Low-Noise Amplifiers

General Description

The MAX2692/MAX2695 low-noise amplifiers (LNAs) are designed for WLAN/WiMAXM applications. Designed in Maxim’s advanced SiGe process, the devices achieve high gain and low noise figure while maximizing 3rd-order intercept point.

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).

Bump Description

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

�� Maxim Integrated Products 6

devices integrate an on-chip output matching to 50I at the output, eliminating the need for external matching components. Table 1 and Table 2 list typical device S parameters and Kf 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 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.

Applications Information

A properly designed PCB is essential to any RF microwave 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.
