Direct down conversion, and its companion, very low IF (VLIF) or near-zero IF, are approaches that have essentially changed the face of the receive chain in a mobile handset. For the designer, it is ...

Direct conversion (or low IF) receiver designs have been in existence for many years. They are widely used in mobile phones and cordless telephones because of their simplicity and lower cost. However, ...

Also called a "tuned radio frequency" (TRF) receiver, it is a radio receiver that detects and demodulates the carrier signal broadcast by the station without using an intermediate frequency (IF) stage ...

But the direct-conversion receiver's biggest problem relates to isolation. Any leakage in the local oscillator frequency that couples into the mixer is at the same frequency as the wanted signal, so ...

NORWOOD, Mass.--(BUSINESS WIRE)--Analog Devices, Inc. (NASDAQ: ADI) announced today an integrated direct conversion receiver development platform for radar systems where reduced size, weight and power ...

Zero IF receivers have had limited success in high performance systems, such as wireless basestations, due primarily to their limited dynamic range. Until recently, most basestations needed to only ...

A direct conversion radio receiver takes a high frequency input signal, often in the 800MHz to 3GHz frequency range, and utilizes one mixer/demodulator stage to convert the signal to baseband without ...

Over the winter, [Michael LeBlanc] thought a good way to spend his time during those long dark nights would be to scratch build his own direct conversion receiver. He was able to find plans for such a ...

Low power semiconductor specialist, CML Microcircuits has added a new Direct Conversion Receiver IC (DCRx) to its family of rf integrated circuits. The CMX994 targets the next generation of multimode ...

Sponsored by Texas Instruments: Pushing beyond the superheterodyne, direct-sampling receivers can help meet the demands of today’s communications systems, but they need ultra-fast ADCs to make them ...

If the Wireless LAN market is still growing, Wireless LAN solutions are already in a cost reduction phase. Conceiving WLAN solutions nowadays requires a high-level approach where the final chipset may ...
