Specifications include: Insertion loss: <6 dB (2 to 12.4GHz), <10 dB (2 to 18GHz) Maximum RF input power is +20 dBm and maximum Repetition rate is >5MHz, Minimum RF pulse width is <50 ns. Pulse input >3 V (on), <0.5 V (off) in normal mode. Impedance is 50-ohms nominal The HP Agilent 11720A features include extremely short rise and fall times (<10 ns) and a high ON/OFF ratio (>80 dB) making it suitable for almost any pulsed RF application. .
This pulse modulator came to us from a retiring electrical engineer who used this in his calibration and product development electronics lab.
