Band Pass Amplifier

The BPA is a battery powered band pass filtered LNA. With greater than 60dB of rejection to the D/L tones in front of the LNA, the BPA-0707A and the antenna probe combine with the iVA to display external PIM products right where they are generated. It makes it easy to detect third order Passive Intermodulation (PIM) Products causing interference in a hostile multi tone test environment. This particular solution helps the Cellular, First Net and Public Safety networks in the 700MHz Band to coexist without interference. With a resultant low noise floor and large dynamic range, the user can walk around and find the offending external PIM source.
