... High-frequency power is taken from the oscillator by attaching a piece of RG-8jU or similar cable to the output coupler at the top of the oscillator. The output coupler may then be rotated and locked in the position to give maximum output. As a receiver, the same procedure is followed and the coupli ...

Differential-to-single-ended converter
... The circuit in Figure 1 addresses applications in which you need to convert a differential-current output to a single-ended voltage. Several analog modules, such as the MC1495 multiplier and the LM1596 modulator/demodulator, provide differentialcurrent outputs. You can adjust R5 to adjust the voltag ...

Oscillator Notes 2
... the Colpitts must be current limited: that is, we allow the active device to go into cutoff for part of the period of oscillation. This reduces the effective gm of the device, averaged over the period, and thus gives the needed gain compression. It also benefits phase noise as we will later see. The ...

TKN IEEE 802.15.4 Symbol Rate Timer for TelosB
... PC every 0.5 s. The clock of the PC was kept stable using NTP. Over a time span of more than 24 hours we counted the number of oscillator “ticks” and compared their sum to the elapsed reference time on the PC. From this we calculated that the average frequency of the boards is 125001.6 Hz and their ...
