IF Variable Gain Amplifier with RSSI

MP

Description

AK1291 is a variable gain amplifier with a power detector. It’s operating frequency ranges from
90MHz to 300MHz. The gain control adopts an analog signal control, and the gain characteristic is dB linear. 
The gain control range is -9dB to +21dB and a dynamic range is 30dB. 
AK1291 has single-ended input and output, with impedance of 50Ω. 
As a typical characteristic, NF is 7dB (at maximum gain) , and IMD3 is 70dBc at output power of -15dBm ,at frequency of 165MHz. 
The power supply voltage is 4.75V to 5.25V.
