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
Table 1.

Technical Description
The SKY65450-92LF is a single-stage, low-noise amplifier with a
bypass switch that operates with a single 3.3 V power supply
connected through an RF choke (inductor L1) to the output signal
(pin 1). The bias current is set by the R1 external resistor. The
device is internally RF-matched and only requires input and out
blocking capacitors C1 and C2 to operate over a frequency range
of 40 MHz to 1 GHz.

Exposure to maximum rating conditions for extended periods may reduce device reliability. 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.
ESD HANDLING: 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 when handling or transporting. Static charges may easily produce
potentials of several kilovolts on the human body or equipment, which can discharge without detection.
Industry-standard ESD handling precautions should be used at all times.
