Can also serve as test transmitter putting out up to 20 mW. Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog 2n43360. Resistor across crustal prevents oscillation at undesired modes. Variable Q feature is controlled by single passive RC network. For equivalent high-pass filter, transpose positions of resistors and capacitors. DC output of low-pass terminal equals DC input plus offset voltages of both opamps.

Adiust resistor values to tune centerfrequency. Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above For high pass, take output from first opamp; for bandpass, take output from second opamp. Opamp can be one section of OPFY. Table gives values of R1 and C1 for three different values of Q. Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz.

Pins 5 and 1 must be connected together for proper operation. DC output of high-pass terminal is equal to offset voltage of integrator.

Starting is reliable and stability is good. L1 trims crystal frequency. Datashewt is 9 tums No. Use R2A to trim bandwidth to exactly 0. Quartz crystal should be cut for operation in series-resonant mode.

With minor modifications, same circuit can be used for and kHz crystals. Finally, trim center frequency to exactly 1.

Damping is in range ofwith critical value of 1. When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears. For Q of 3, feedback resistor should be 36 times value of input resistor. Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance.

Q is changed by varying ratio of input and feedback resistors while keeping their product constant.

Q1 can be 2N or T1M If R9 is advanced far enough with switch set to pass, 2n430 will oscllate and give sine-wave output datashewt tuned frequency. Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results.

Maximum selectivity, conesponding to maximum height of pass curve or depth of reject curve and minimum width of either curve, is obtained when R9 is set for maximum gain in FET Q4.

Oscillator uses two stages, one oporating in class A and the other datasheet as limiter that also serves as feedback path. Both outputs have DC continuity. Altemative opamps can be and Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency.

Dynamic output impedance of both outputs is less than 1 ohm.
