To produce a variable phase-shifter at low cost and method of manufacture, easy, there is provided between the inlet (1) and the output (2) of the phase shifter to produce two paths (3, 4) of propagation of a high frequency signal in parallel. These two paths are of different lengths...
SYMES: "A voltage controlled phase shifter" Claims: 1. A clock-delay circuit for a sinusoidal clock output wave comprising: (a) a first amplifier means responsive to said output wave for producing a first amplified signal in phase with said output wave; (b) a second amplifier means ...
A dual鈥恇and vector鈥恠um phase shifter with independent phase control of the 2.4 and 5聽GHz Wi鈥怓i bands is presented. The network uses band鈥恖imited variable gain amplification, with a broadband hybrid coupler at the input and an in鈥恜hase recombiner at the output. The circuit is ...
A variable phase shifter having a substantially wide phase shift variation range is formed of more or less standard circuit elements such as inductors, capacitors, quadrature hybrids and variable capacitors (or varactor diodes), the circuit elements being connected to one another in a fashion particul...
athe first signal passes through a variable attenuator (controlled by the voltage sent from a “Temperature Compensation Circuit”), a phase shifter (controlled by CCU), another attenuator and, after being equalized, is amplified and sent to the predriver stage. An RF switch, at the equalizer ...
A method and apparatus for a phase shifter includes a controller controlling a voltage controlled phase shifting circuit for shifting the phase of a high frequency input signal. The phase shifting circuit includes microstrip elements arranged in a 3 dB hybrid structure, and also includes first and ...
If an electronic circuit is necessary to convert or interpret the signals exchanged, these circuits will also be attached and/or integrated to the extractible module held by the plate 7. FIG. 3 shows an embodiment of the extractible module. On this figure, the plate 7 is not installed. ...
