WebJun 27, 2024 · A standard mixer application is translating a signal between the RF frequency and the IF frequency (you were warned!). In both cases one of the input signals is the local oscillator (LO). For the receive chain, … WebDec 18, 2014 · In this paper, a double-balanced Gilbert cell down-conversion mixer is demonstrated from 70-110 GHz. The wide bandwidth and high frequency are enabled by the HRL InP/Si BiCMOS process. With an fT of 300 GHz, the available 0.25 μm InP HBTs are used in the signal path while the 90 nm CMOS devices are used for biasing and gain …
Tips for Simulating a Transmit Mixer in SpectreRF
WebDigital Down Conversion is a technique that takes a band limited high sample rate digitised signal, mixes the signal to a lower frequency and reduces the sample rate while retaining all the information. ... A Digital Down Converter is basically complex mixer, shifting the frequency band of interest to baseband. Webmixer, so that no down-converted image is allowed to be generated by the mixer. Since the desired and image signals are always sepa-rated in frequency by twice the IF frequency, the IF frequency must be high enough to allow the preselector in front of the mixer to block the image, but still allow the desired if signal to enter the mixer. cheryl chou singapore

WebJun 6, 2000 · In a direct conversion receiver, however, mixer non-linearities of second order will result in the down conversion of any signal, presented to the mixer input, to a baseband signal. A pure carrier will thus give rise to a DC signal at the output, while an AM modulated signal will result in a low-pass baseband signal whose spectral contents ...
