Wideband High Gain Preamplifier: To 18 GHz Com-Power PAM-118A

I Introducing Com-Power PAM-103:

The PAM-103 Model Com-Power preamplifier is designed to improve measurement system sensitivity during EMC compliance testing. It has a frequency range of 1 to 1000 MHz.. It has a gain of 33 dB. Therefore, It amplifies signals previously hidden below the EMI receiver’s noise floor to become visible and measurable. The PAM-103 has ±3 dB variable gain for the entire frequency range to reduce measurement errors. It can be powered by a rechargeable NimH battery when an external power source is not available.
