KC95021 RF Demo Kit is specially designed for RF Network Analyzer learners. It contains totally sixteen types or RF circuits, among which eleven types are single-port networks, and five are dual-port networks. Also there are directive multi-stage antennas embedded within that can be used for both signals reception and emission. Furthermore, it is equipped with three well-performing (open-short-load) calibrators that are fit for UFL connectors with 1mm electrical length, which the operator can perform calibration with on the VNA before measuring the PCB antennas. Frequency Range of Multi-Stage Antenna (VSWR <2) 560MHz – 600MHz 1430MHz – 1700MHz 2450MHz – 2670MHz 3200MHz – 3670MHz 4100MHz – 4500MHz 5100MHz – 5970MHz The Return Loss of LOAD Calibrator Better than 20dB (<2.5GHz) Better than 10dB (2.5GHz – 7GHz) Pre-set the measuring frequency range on the VNA first, and then connect the VNA to Demo Kit with a UFL cable to perform calibration, there the operator can start RF network measuring.
