The module includes a trimmable capacitor (110) (410) having metal plates (112, 114), (412, 414, 416) capacitively coupled through the substrate.

Abstract: A two-stage direct conversion receiver. A first mixer (13) converts the incoming signal to an intermediate frequency (IF) signal. A second mixer (16) converts the IF signal to a baseband signal. A detector (17), receiver logic circuit (18), and alerting device circuit (19) act upon the baseband output signal. A two port oscillator (14) provides a fundamental frequency output (FO) and a tripled output frequency (3 FO). The tripled output frequency is again tripled (9 FO) by a frequency multiplier (15) and is provided as a mixing signal to the first mixer (13). The fundamental frequency output is provided to a phase locked loop (20, 21, 22). The output frequency (FV) of the phase locked loop is doubled (2 FV) by a frequency multiplier (23) and provided to a phase shift circuit (24). The output of the phase shift circuit (24) is provided as the second mixing signal to the second mixer (16). The phase locked loop comprises a phase locked loop controller (20), a phase locked loop filter (21), and a voltage controlled oscillator (22). The main oscillator (14) is configured as a crystal controlled Colpitts oscillator, which has an emitter resonant circuit selected to produce oscillation at the fundamental frequency, and a collector resonant circuit selected to extract the third harmonic of the fundamental oscillation frequency. A single active device can therefore provide both the fundamental frequency and the third harmonic frequency. Calibration of the receiver is effected by simply tuning the oscillator (14) to produce a baseband output signal at the output of the second mixer (16). Single step calibration is therefore effected because the voltage controlled oscillator (22) is locked to the main oscillator (14).

Abstract: An RF oscillator and modulator especially useful for UHF applications. The oscillator may comprise a series-tuned Colpitts circuit with the tuned circuit including microstrip transmission lines as impedance elements. The modulator includes a pair of serially connected diodes with the common terminal of the diodes receiving a modulation signal which varies the total current through the diodes. The diodes function as current-variable resistances to attenuate the carrier frequency signal in response to the modulation signal.

Abstract: An oscillator for producing an output signal having a predetermined frequency for use in an electronic timepiece. The oscillator comprises a miniature crystal vibrator having a high resonant frequency, a case housing the crystal vibrator, an integrated circuit comprising an oscillator circuit with the crystal vibrator, and a trimmer condenser for adjusting the high resonant frequency. The trimmer condenser is formed on an external recess portion of said case, and is connected with the crystal vibrator and integrated circuit by a circuit having low stray capacitances. The oscillator is therefor highly insensitive to external electric fields.

Abstract: The oscillator comprises a feedback amplifier (10) consisting of an FET (106) and a varactor diode (3) acting as a load-coupling capacitor. A part of the output from the amplifier is supplied as oscillation output to an external load (300) including a high-output amplifier and an antenna device. The varactor diode has a junction capacitance which varies according to the bias voltage applied to the diode. This diode capacitively couples the amplifier to the external load through the variable junction capacitance. Therefore, the capacitance value of the load-coupling capacitor can be changed by adjusting the bias voltage. Thus, the variation of the capacitance of the load-coupling capacitor caused by design errors or by variations of the conditions of the manufacturing process can be easily corrected when the device is in use. In consequence, the oscillator can be operated always with good oscillating characteristics without hindering integration of individual components or a reduction in the cost.
