Description
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-to-
baseband 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.
The device package and pinout for the 16-pin LGA are shown in
Figure 1 and a block diagram of the SKY74092-11 is shown in
Figure 2.
