Description
The ISL74324M is a radiation tolerant 500MHz to 6500MHz SiGe BiCMOS high-gain broadband radio-frequency (RF) amplifier. The combination of a low noise figure (NF) and high linearity performance allows the device to be used in both receiver and transmitter applications.
The ISL74324M operates with a single 5V or 3.3V power supply using a nominal 60mA. With a supply voltage of 5V, the ISL74324M provides 16.6dB gain with +38.4dBm OIP3 and 2.2dB noise figure at 4200. Additionally, it is bias adjustable and can be operated as low as at 40mA for improved efficiency. This device incorporates a convenient shutdown capability through the STBY pin.
The ISL74324M is packaged in a 3mm x 3mm, 16-pin QFN with 50Ω single-ended RF input and output impedances for ease of integration into the signal path.
