    [SOLVED] Part in circuit board

    Hello, Can someone inform me what is the component between the 1K resistor and the BT137 triac?

    RF power amplifier efficiency in keysight ADS

    Thank you for your answer. Is this equation valid though? Can I just replace the RF output with DC?

    RF power amplifier efficiency in keysight ADS

    Yes only the first harmonic P_Probe2.p[1]. But is there a formula for calculating efficiency of the DC output power to RF input power?

    RF power amplifier efficiency in keysight ADS

    Is the below equation valid to calculate RF power amplifier efficiency? Probe4 is placed right before a resistor where DC voltage component of the amplified RF OUT power is supposed to be measured and Probe2 measures RF power IN.

    Keysight ADS P_1Tone

    Thank Thank you for your answer. I have managed to increase the value to 0.9 mW by adding a microstrip line in series with an inductor in series with a resistor. Is this configuration valid since I have not based it on any available matching circuit configuration ( I just added them arbitrarily)?

    Keysight ADS P_1Tone

    Thank you for your answer. I tried using the P_Probe1 but I get 0.2691 mW instead of 1mW (0 dBm).

    Keysight ADS P_1Tone

    When I plotted the dBm(RF_IN) I obtain -9 dBm right after the RF source which is set at 0 dBm (see images below) . I do not understand why I did not obtain 0 dBm in the plot.

    schematic in keysight ADS issue

    Thank you for replying. You are referring to the 0 GHz right? What do you recommend to modify to increase the DC value ? 1682591807 Also, I am interested only in 2.4 GHz and not the other frequencies. Or is it that for all frequencies the values should be high ?

    schematic in keysight ADS issue

    Thank you for replying. So I have tried to do HB simulation. I modified the circuit as shown below (I removed the 1 nF and 1 MOhm) and added a Term in series with the diode. I obtained 2.999 dBm for the 2.4 GHz. Am I on the right track now? Please advise me if I am not as any suggestion would...

    schematic in keysight ADS issue

    Thank you for replying. The schematic is based on the 2 circuits shown below so from RF OUT we get an amplified signal which should be rectified by the schottky diode in the other circuit shown. I thought it might work but I guess not. Do you have any suggestions on how I should modify the...

    schematic in keysight ADS issue

    In the circuit below (both images are 1 entire circuit), I measured DC voltage at Vout and I obtained 0 V. The circuit is basically a power amplifier + power detector (with schottky diode) for RF source. This is the first time I use keysight ADS and I am not sure where I went wrong.

    2.4 GHz RF signal generator

    In Proteus, the schematic, is there a component to represent 2.4 GHz signal generator ?
