Description

The SKY65452-92LF 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 SKY65452-92LF 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 SKY65452-92LF 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.

3 NC Not connected 6 RFIN RF input

Technical Description

The SKY65452-92LF 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.

CAUTION: 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. Static charges may easily produce potentials of several kilovolts on the human body

or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Evaluation Board Description

The Skyworks SKY65452-92LF Evaluation Board is used to test

the performance of the SKY65452-92LF low-noise amplifier.

Figure 3 shows an application schematic for the SKY65452-92LF.

An assembly drawing for the Evaluation Board is shown in

Figure 4, and the layer detail physical characteristics are noted in

Figure 5. Typical part marking is shown in Figure 6.

Capacitor C5 provides DC bias decoupling for the output stage

collector voltage. Pins 6 and 1 are the RF input and output

signals, respectively.

External DC blocking is provided on the input and output by

capacitors C1 and C2. Ground pin 5 and the center ground pad

provide the DC and RF ground. Resistor R1 is the bias resistor that

can be used to optimize the current and performance of the LNA

and L1 is a choke inductor which connects the Vcc to the output

stage of the LNA. Pin 2 provides an enable function and has an

optional RC circuit held in place by resistor R2 and capacitor C3.

Pin 3 is a no connect pin and can be left floating or may be

grounded.

The input and output RF traces are 75 Ω traces.
