the sawtooth-wave circuit of complementary tube

Published:2011-6-30 6:11:00 Author:Fiona | Keyword: sawtooth-wave, complementary tube

The picture shows the sawtooth-wave circuit of complementary tube.This is self-oscillating complementary sawtooth-wave circuit which the switching device is composed of BG1,BG2 and controls the timing capacitor C to charge and discharge,BG3 is constant flow pipe.When BG1, BG2 are closed, the constant current Ic3 charges to C(polarity is shown as the picture) the output voltage uo decreases with linear time, this is a scanning voltage positive process, when the capacitor voltage Uc drops to the BG2 conduction valve voltage, BG2 starts to conduct,BG1,BG2 arrive at the saturated state after a positive feedback chain reaction,at this time, when you reach a saturation point C remains at saturation without returning to the OFF state through BG1, BG2.   (View)

The typical application of AD8318 is as shown in the figure. The AD8318 is designed to measure the 8GHz RF power, so the insulativity of the IN+, IN- pins and functional unit circuits is very important. The positive power supply port UPSI and UPSO must be connected to the same voltage, the UPSI port supplies the bias voltage to the input circuit, the UPSO port supplies the bias voltage to the low-noise output driver of the UOUT port. There are some independent public places in the AD8318. The CMOP can be used as the public place of the output driver. All the public places need to connect with the low impedance PCB ground area.   (View)

The typical application of LTC5507

Published:2011-7-6 3:11:00 Author:Christina | Keyword: typical application

The typical application of LTC5507 is as shown in the figure. C1 is the coupling capacitance of the RF input port, C2 is the peak keeping capacitance, both of C1 and C2 use the ceramic capacitor, the capacitive reactance is lower than 5Ω to reduce the ripple wave of C2. The capacities of C1 and C2 depend on the minimum input frequency fmin of the RF (the unit is MHz), the formula is C1=C21≥(30fmin). In this formula, the units of C1 and C2 are μF. Because the value of C2 will affect the conversion rate and the bandwidth, so C1=C2. The capacities of C1 and C2 can not be too large, or the frequency will exceed the minimum input RF frequency.   (View)
