SKY67012-396LF Block Diagram Description The SKY67012-396LF 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 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 SKY67012-396LF is manufactured in a compact, 2 x 2 mm, 8-pin Dual Flat No-Lead (DFN) package. A functional b...
