Additional Typical Specifications:

Out of Band Harmonic Rejection (10 to 20GHz): -30dBc

Maximum RF Output Power: +18dBm with Pin = -60 to 0dBm

Operating Temperature: 0 to +70°C

Other Frequency and Gain Levels Available.

Attenuation Control: (External Resistor)

The amount of gain attenuation is controlled by the value of the resistor placed between the control pin and ground.  Typical values yield the following results.

Resistor values in Ohms:

260 = -1dB, 147 = -2dB, 101 = -3dB, 78 = -4dB, 63 = -5dB

The variable gain amplifier above provides 30dB of gain with up to 5dB of attenuation control.  The amount of attenuation is selected by placing a resistor between the control pin and ground.  This type of amplifier is useful if fine gain calibration adjustments are required in a system.

      

All specifications are typical and subject to change with or without notice.
