High-Gain Broadband RF Amplifier
600MHz to 4200MHz
F0424
Datasheet
Description
The F0424 is a 600MHz to 4200MHz SiGe High-Gain Broadband
RF Amplifier. The combination of low noise figure (NF) and high
linearity performance allows the device to be used in both receiver
and transmitter applications.
The F0424 is designed to operate with a single 5V or 3.3V power
supply using a nominal 70mA of ICC. With a supply voltage of 5V,
the F0424 provides 17.3dB gain with +40dBm OIP3 and 2.3dB
noise figure at 2600MHz.
This device is packaged in a 2mm 2mm, 8-pin Thin DFN with
50Ω single-ended RF input and output impedances for ease of
integration into the signal-path.

Pin Descriptions
Name
Description
VCC Power supply. The bypass capacitor must be as close to the pin as possible.
RFIN RF input internally matched to 50Ω. An external DC block is required.
NC
No connection. This pin can be left unconnected, connected to VCC, or connected to GND. IDT
recommends connecting it to GND.
RSET Main amplifier current bias setting resistor. Connect to GND.
RDSET Distortion amplifier current bias setting resistor. Connect to GND.
STBY
Standby. If this pin is not connected or is logic LOW, the device will operate under its normal operating
condition. If this pin is logic HIGH, the F0424 will be in STBY Mode.
RFOUT RF output internally matched to 50Ω. An external DC block is required.
i.c. Connect this pin directly to ground
Exposed pad. This pad is internally connected to GND. Solder this exposed pad to a printed circuit board
EP (PCB) pad that uses multiple ground vias to provide heat transfer out of the device into the PCB ground
planes. These multiple ground vias are also required to achieve the specified RF performance.

Absolute Maximum Ratings
The absolute maximum ratings are stress ratings only. Stresses greater than those listed below can cause permanent damage to the device.
Functional operation of the F0424 at absolute maximum ratings is not implied. Exposure to absolute maximum rating conditions may affect
device reliability.
