Abstract
The present invention describes a receiver assembly for receiving an analog signal and converting the analog signal to a digital signal. The receiver assembly is, preferably, capable of receiving a signal operating at approximately 60 GHz. The receiver assembly includes a filter, a down converter, a demodulator, a latch, a FIFO, and a logic circuit. A method of converting the 60 GHz analog signal to a digital signal is also described.
Claims11
A receiver assembly comprising:
- an N-array antenna assembly having a plurality of antennas, wherein the plurality of antennas are adapted to operate at a bandwidth of approximately 60 GHz;
- a plurality of amplifiers, one of the amplifiers of the plurality of amplifiers being in communication with one antenna of the plurality of antennas of the N-array antenna assembly for the amplifying of a signal received by each antenna;
- a down converter for performing frequency conversion of an amplifier signal being emitted by each amplifier of the plurality of amplifiers;
- a demodulator adapted to recover data and recover clock signals from the down converter;
- a latch for realigning clock signals from the demodulator, wherein the latch is based on a bit rate of a clock signal from the demodulator;
- a first-in/first-out circuit for organizing and recovering the clock signal from the latch;
- and
- a logic circuit adapted to correct errors in a signal from the first-in/first-out circuit.
A method of converting an analog signal to a digital signal, wherein the analog signal has a bandwidth of approximately 60 GHz, the method comprising:
- receiving the analog signal operating at approximately 60 GHz with a plurality of antennas;
- feeding the analog signal received from the plurality of antennas to a amplifier;
- amplifing the analog signal to create a cleaned signal;
- converting the frequency of the cleaned signal by down converting the cleaned signal;
- demodulating a down converted signal;
- synchronizing a demodulated signal;
- and
- correlating the signal to known sequences.
