In constructing this rf switch circuit, all wirings must be as short as possible to avoid picking up interferences. Coils L1…L5 are 2 turns magnet wire (1µH) around a ferrite core for VHF range. For UHF range, the coil must be 5 turns (5µH). The PIN diode switch can be us...
In this, the 555 timer used is in free running astable multi-vibrator mode at a frequency of 38 KHz and a duty cycle of about 60%. The said pulses drives a transistor Q2 the collector of which powers an IR diode D1 through 100Ω resistor from the power supply 6V DC. As the receivi...

Practical Design Hints PIN diode circuit pertormance at RF frequencies is predictable and should conform closely to the design equations. When a switch is not performing satistactorily, the fault is often not due to the PIN diode but to other circuit limitations such as circuit loss, bias ...
2. For output currents lower than this value a series protection diode can become active. See also Figure 5 and 7. 3. Speed limitation related to external capacitance Cext RX, LO and internal impedance CLO, RX, RLO, RRX for rise time. tr = RLO, RX · (CLO,RX + Cext RX, LO) ...
Dear all, We would like you to check circuit diagram. Please see attachment file. This pin has absolute maximum about voltage and current value. Is this circuit OK? LM73 absolute maximum ratings.pdf Best regards, Hi Yamamoto-san, The diode which you drew, titled "Equivalent Cir...
by looking at the diagram in FIG. 3, it can be noted that, in a circuit having a characteristic impedance Z.sub.0 of 50 ohms implemented according to the technique known so far, the attenuator decoupling varies from 25 to 43 dB in correspondance to pin diode resistances ranging from 10 ...
In the case when no large input Both of these circuit blocks employ sensitive semiconductor signal is present, the impedance of the limiter diode is at its components that will very likely be damaged by even a small maximum, thereby producing minimum insertion loss, typically portion of the ...
