AD8367 500MHz RF Broadband Signal Amplifier Module 45dB Linear Variable Gain AGC VCA 0-1V

Product application AD8367 is ADIs X AMP structure of variable gain IF amplifier consists of a 9 order resistance attenuation network and a fixed gain amplifier enables accurate log linear gain control gain control range of 45 dB it can not only configure plus traditional VGA mode applied voltage control while also incorporates square law detector which can also operate in AGC mode AD8367 typical operating frequency range of less than 500 MHz has two operating modes positive gain mode MODE Termination high and a negative gain mode MODE Termination low analog gain control voltage range of 50mV 950mV control sensitivity of 20mV dB can be set by the AGC gain control terminal MODE is positive or negative gain control mode gain control mode to match the characteristics of logarithmic amplifier constituting stable negative feedback AGC circuit When operating at positive and negative gain control mode the relationship between the logarithmic and linear gain control voltage between AD8367 are positive gain mode G 50Vc 5 dB negative gain mode G 45 50Vc dB where G is the gain in units of dB Vc is the control voltage in volts Module has a shield housing and anti reverse protection diode Technical indicators 1 power supply voltage 5V DC typical current 200mA maximum gain output 2 the operating frequency DC 500MHZ input and output impedance 50 ohms 3 the maximum output amplitude 27dbm 200 ohms 4 a variable gain range 46dB see specific
