Abstract
A hybrid digital electronic tuner (HDET) uses a modified forward signal power injection technique, a variance of a prior art Gamma Boosting Unit (GBU) technique, cascaded with a digital, PIN diode based, electronic tuner, all integrated in the same low loss parallel plate airline (slabline) to create a compact hybrid tuner unit able of generating thousands of high reflection factors (|Gamma|≥1) at millisecond tuning speed.
Claims8
A hybrid digital electronic impedance tuner (HDET) comprising two modules,
- a) an active tuner module, and
- b) a passive tuner module,
- wherein
- the active module comprises two ports, an input (test) port and an output (idle) port, and
- a slotted airline (slabline) between the ports, two directional signal couplers (wave-probes) and an amplifier;
- wherein
- the slabline comprises metallic, grounded sidewalls, a center conductor between the ports and the two wave-probes, of which one is fixed and one is mobile,
- and wherein
- each wave-probe comprises a coupled port and an isolated port,
- and wherein
- the mobile wave-probe is attached on an adjustable vertical axis of a mobile carriage, said the vertical axis controlling the penetration of the mobile wave-probe into the slot of the slabline,
- and wherein
- the carriage slides across the length of the slabline;
- and wherein
- the passive tuner module comprises a multitude of RF electronic switches (PIN diodes), and is incorporated in the section of the slabline between the active module and the output port.
