SKY74092-11 Dual-Band LNA for CDMA, Femtocell, and PCS Mobile Handset Applications

The SKY74092-11 is a dual-band Low Noise Amplifier (LNA) intended for use in Code Division Multiple Access (CDMA) portable phones in both cellular and Personal Communications Service (PCS) bands. The device provides low noise amplification with high linearity to achieve high dynamic range. Together with SKYWORKS SKY74100 direct conversion receiver, the SKY74092-11 offers a cost effective, high performance RF-tobaseband radio solution. By cascading the SKY74092-11 with the SKY74100 DCR™, Printed Circuit Board (PCB) layout can easily be optimized for small areas and easy routing. Different modes, currents, and gain steps of low noise amplification are controlled by a serial three-wire bus interface. The device requires external supply filtering capacitors, one bias resistor, and various external components to match input and output impedance to 50 . The SKY74092-11 is provided in a 3 x 3 mm Land Grid Array (LGA) package.
