描述 Description

The SKY65450-92LF is a Microwave Monolithic Integrated Circuit

(MMIC) front-end low-noise amplifier (LNA) designed especially

for set-top box applications. The device provides high linearity,

excellent gain, and best-in-class composite triple beat (CTB) and

composite second order (CSO). There are minimal external

components.

The SKY65450-92LF is optimized to operate between 40 MHz and

1 GHz, which makes it ideal for cable and terrestrial set-top box

and home gateway applications.

The SKY65450-92LF is fabricated using SiGe BiCMOS technology.

The LNA uses surface-mount technology (SMT) in a 6-pin SC-70

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
