Communications receiver architecture has evolved slowly over the years. The most common and successful configuration is the superheterodyne architecture, which translates the incoming signal to a ...

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 ...

Two new direct conversion quadrature demodulators from Linear Technology Corporation simplify radio design for cellular basestations and microwave and satellite links. Linear Technology's LT5515 and ...

The critical component in all digital communications receivers is the analog-to-digital converter (ADC). The ADC sampling rate, bandwidth, and noise tolerance establishes the specifications and ...
