M9379A RF Amplifier
Overview
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 analyzer (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. When combined with the direct access receivers and high-power coupler in the M9485A, the dynamic range can be increased which is suited for high-rejection filter measurements.
Key specifications/features
Specifications
Definitions
Specification (spec.):
Warranted performance. All specifications apply at 25 ºC (± 5 ºC) range ambient and module temperature between 28 ºC to 42 ºC as reported by the module, unless otherwise stated, and 45 minutes after the M9379A amplifiers and switches have been turned on 1 . Specifications include guard bands to account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions.
Typical (typ.):
Expected performance of an average unit which does not include guardbands.
General characteristics:
A general, descriptive term that does not imply a level of performance.
Boundary conditions
If the same boundary conditions fall under more than one category in a table, apply the best value.
