However, the torque magnitude has little impact on the
intermediate frequency and high frequency intervals.
Now that we've chosen an acceptable
Intermediate Frequency we are in a position to select a mixer.
The R2S15500SP converts Sound
Intermediate Frequency (SIF) into digital data processing demodulation.
In addition, the chip cuts the external component count, and therefore cost, by eschewing IF (
Intermediate Frequency) filters, ceramic capacitors, and varicaps.
The system provides two receive and one transmit channel at industry standard 213.33 megasamples per second (MSPS) supporting a 160-MHz
intermediate frequency (IF) with bandwidths in excess of 80 MHz.
The low-IF (
Intermediate Frequency) radio receiver architecture employed in this design, adapted from high-efficiency pager technology, offers lower power consumption and better immunity to interference than direct conversion receivers.
Either the
intermediate frequency (IF) or the RF signal is mixed with the LO signal, resulting in the frequency up- or down-conversion operation.
Like all members of the MSM6xxx family, the MSM6280 solution incorporates QUALCOMM's radioOne Zero
Intermediate Frequency (ZIF) architecture, which eliminates the need for
Intermediate Frequency (IF) components.
Also, the absence of
intermediate frequency noise enables much simpler RF planning inside the complex environment of a cell phone.
There are 10 digital signal processor (DSP) chips inside a Symphony radio, of which nine are special purpose co-processors supporting a 24-bit core unit that contains the radio frequency (RF) front-end and
intermediate frequency (IF) analog interface.
