VBIAS 1 8 N/C RF_IN 2 7 RF_OUT/VDD N/C 3 6 N/C N/C 4 5 N/C The SKY67015-396LF is a GaAs, pHEMT low-noise amplifier (LNA) with an integrated active bias. The advanced GaAs pHEMT enhancement mode process provides excellent return loss, low noise, and high linearity. The SKY67015-396LF is typically used at frequencies ranging from 100 MHz to 300 MHz, The device has been successfully tuned down to 30 MHz with the addition of external RC feedback. Please contact Skyworks for details. The device offers the ability to externally adjust the supply current. The supply voltage is applied to the RF-OUT/VDD pin through an RF choke inductor. The VBIAS pin should be connected to the RF_OUT/VDD pin through an external resistor to control the supply current. Both RF_OUT/VDD and RF_IN pins should be DC blocked to ensure proper operation. The SKY67015-396LF is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) package. A functional block diagram is shown in Figure 1. The pin configuration and package are shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. S2396 Figure 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 value. 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. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY67015-396LF are provided in Table 2. Electrical specifications are provided in Tables 3 (18 mA operation) and 4 (5 mA operation). Typical performance characteristics of the SKY67015-396LF are illustrated in Figures 3 through 15.
