Com-Power PAM-103 Preamplifier 1 MHz – 1000 MHz

Description

The model PAM-103 are general purpose, broadband, high gain, bench top preamplifiers. These preamplifiers reduce floor noise and increase system sensitivity to low level signals during Electromagnetic Interference (EMC) testing. They also provide input isolation to your expensive test equipment. The PAM-103 has a frequency range of 1 MHz to 1000 MHz. The simple front panel consists of two 50 ohm matched BNC connectors for input and output. The preamplifiers were designed to have minimal gain variation for the entire frequency range to reduce EMC measurement errors.

Power to the model PAM-103 is supplied by a 12 VDC, 500 mA external wall mount adapter. The preamplifier can also be powered by batteries for field use. The same adapter charges the internal re-chargeable battery pack.

Features

  • Broadband - 1 MHz- 1000 MHz
  • High Gain: 33 dB
  • Flat Response: ±3 dB
  • Individual Calibration

Com-Power PAM-103 Application

The PAM-103 is primarily used for EMC radiated emissions testing. These preamplifiers can be used during EMC testing for FCC, CISPR, EN, FAA and MIL-STD. This preamplifier could also be used in other applications that require a high gain preamplifier.

The enhanced system sensitivity due to high gain is very helpful when making EMC measurements using antennas on an Open Area Test Site (OATS) or probing a printed circuit board using Near Field Probes. This allows measurements of those frequencies from the equipment under test, that are not visible on the spectrum analyzer display unless amplified. The preamplifier gain will cause peaks to be visible above the background noise of the analyzer. These frequencies may go undetected if a preamplifier with a high gain was not used.

In addition, preamplifiers could improve sensitivity of counters and power meters. The PAM-103 can also be used to increase the available power from your sweeper or signal generator.
