Description The SKY65404-31 is an ultra low-noise amplifier (LNA) intended for 5 GHz wireless receiver applications. Its industry-leading noise figure (NF), together with high linearity, makes it ideal as a firststage LNA in 802.11a wireless local area network (WLAN) radios. Operating with a single supply voltage, the SKY65404-31 consumes only 10 mA of current. The device includes a shutdown mode to save power when the receiver is inactive. The tiny package footprint of the SKY65404-31, requiring only four external components, enables the industry’s smallest PCB area needed to implement a 5 GHz LNA. A block diagram of the SKY65404-31 is shown in Figure 1. The device package and pinout for the 6-pin Quad Flat No-Lead (QFN) are shown in Figure 2. Signal pin assignments and functional pin descriptions are described in Table 1. V_ENABLE 1 6 VCC GND 2 5 GND RF_IN 3 4 RF_OUT S1351 Figure 2.

SKY65404-31 Pin Assignments and Signal Descriptions Pin 1 Name Description V_ENABLE Enable control input 2 GND Ground 3 RF_IN LNA input 4 RF_OUT LNA output 5 GND Ground 6 VCC Supply voltage for LNA Technical Description Electrical and Mechanical Specifications The SKY65404-31 is matched at the RF output port (pin 4) and requires only a shunt capacitor match at the RF input port (pin 3). The VCC signal (pin 6) requires a simple bypass circuit. An external resistor on the V_ENABLE signal (pin 1) allows a wide range of control voltages to be used. Shutdown mode is achieved by switching the V_ENABLE signal to 0 V. The absolute maximum ratings of the SKY65404-31 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Table 5 provides the control logic for the SKY65404-31. Performance characteristics for the SKY65404-31 are illustrated in Figures 3 through 9. Table 2.

There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal values. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, electrostatic discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.
