Preamplifier 33 dB Gain and Wideband: 1 to 1000 MHz

(855) 364-2362

The PAM-103 is a low-noise, high-gain preamp covering 1 MHz to 1 GHz frequency range.
It delivers 33 dB gain with a noise figure below 3.3 dB, ideal for EMI test systems.
Powered by internal battery or AC adapter, it runs over 13 hours per full charge.
Durable aluminum housing with N-type connectors ensures long-lasting performance.
Battery and charge indicators help maintain stable, consistent gain during operation.
It improves measurement accuracy by lowering the system noise floor in EMI tests.
Each unit includes NIST-traceable calibration; ISO 17025 certification is available.
