radio frequency integrated circuits (RFICs) have become complex chips both by themselves and integrated into very largesystem-on-chip (SoC)solutions. An RFIC is designed to operate at
Only one mixer is used from the RF port to the host. Therefore, this USRP uses a homodyne structure. However, not all USRPs utilize this structure. For example, in the case of the USRP-2945, the block diagram shows that there is an IF stage. Therefore, this product utilizes a heterody...
While the switch is closed R1 dissipates oodles of power by virtue of C1's smoothing effect. If R1 is an antenna, power is re-radiated at many frequencies. Not good. Very often, a second similar mixer circuit is used to take advantage of the first mixer's off-period to d...
A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize,modulate, demodulate, filter or recover a signal from a "noisy" communications channel where d...

devices. If you have multiple teams or frequently changing set-ups, this tool will save you a lot of time because you can save and recall all those different profiles . If you are looking to use a myMix Install to provide sound to an overflow room, the locking function is an extra ...
As mentioned above, superheterodyne or superhet radio works by using a variable frequency local oscillator and an RF mixer. The incoming signals and the local oscillator signals enter the RF mixer and thee incoming signal is converted down to a fixed frequency intermediate frequency stage that ...
The RF design of the radio should ensure that the mixer is not overloaded. To achieve this there should not be excessive gain preceding it. Also a high level mixer should also be used (i.e. one designed to accept a high-level local oscillator signal). In this way it can tolerate high...
Added a Hybrid Source driver, which combines a source and a mixer to create a high-frequency source. This new driver selection appears the External Device Configuration dialog. What's New in VNA Code Version A.16.20.xx Added new SCPI Example Programs in Python Environment ...
A crystal unit is an electronic component that uses the piezoelectric effect of a quartz crystal to generate accurate signals and stable frequencies for operating electronic devices. Since a quartz crystal unit by itself cannot output clock signals, it is always used in combination with an oscillatio...
