The M9379A RF Amp Module includes two amplifiers, RF switches, and a programmable step attenuator designed to operate with the M9485A and M980xA PXIe vector network analyzers (VNA). One of the internal amplifiers works as a programmable pre-amp containing two user-selectable paths, either an amplifier path with a variable gain using a step attenuator or bypass path. The M9379A can improve the noise floor of the measurement system with the M980xA PXIe VNA. For example, the M9379A with a pre-amp is an ideal solution for noise figure (NF) measurements using the M980xA's standard receivers up to 13.5 GHz. The 1-slot module also includes internal switches which are directly controlled by the M980xA's firmware, enabling synchronized fast measurements for both S-parameters and NF with the PXI system.

The M9379A RF Amp Module includes two amplifiers, RF switches, and a programmable step attenuator.

• Dual amplifiers improve S/N ratio of VNA receivers
• Synchronized NF measurements with the VNA
• Frequency: 50 MHz to 13.5 GHz
• > +21 dBm saturated output power at 3 GHz (typ.)
• > 25 dB forward gain at 3 GHz (typ.)

Exceptional gain (25 dB) and flatness (±1.5 dB) combined with a probe-power bias connection which eliminates the need for an additional DC power supply, makes these preamplifiers the ideal choice for spectrum analyzer or stand alone applications. 

• 4.5 dB noise figure and 25 dB gain helps improve the dynamic range and sensitivity of your test equipment
• High 15 dBm P_1dB increases available power from network and spectrum analyzers
• DC Bias Volt/Amp: +15 V at 140 mA (nominal); -12.6V to -15V at 3mA (nominal)
• Rugged, portable design for ease of use in the field
• Probe-power bias connection eliminates the need for an additional power supply
