The first input path and the second input path propagate a first single-ended input signal and a second single-ended input signal, respectively, to ... 04/27/06 - 20060089115 - Dual band superheterodyne receiver A MMIC based superheterodyne receiver for converting at RF energy in an upper and a lower frequency band includes at least one attenuator for the RF energy input, a mixer for mixing the lower band input with a LO1 signal, another mixer for mixing the upper band input with the ... 03/16/06 - 20060057988 - Low cost planar double balanced mixer A double balanced mixer includes a local oscillator balun, a radio frequency balun and four diodes. The local oscillator balun has a transmission line, a half wavelength transmission line and a quarter wavelength transmission line mounted on a printed circuit board. The radio frequency balun has a transmission line, a ... 01/26/06 - 20060019622 - System and apparatus for a direct conversion receiver and transmitter A system for transmitting and receiving data is provided. The system includes a direct-conversion receiver that receives a signal modulated on a carrier frequency signal. The direct-conversion receiver includes one or more subharmonic local oscillator mixers. A local oscillator is connected to the direct conversion receiver, and generates a signal ... 10/06/05 - 20050221775 - Passive mixer with improved linearity A mixer circuit is disclosed that includes a first mixer stage including first and second transmission gates. The mixer circuit also includes a second mixer stage including third and fourth transmission gates. The mixer further includes a first base band signal terminal coupled with the first and second transmission gates ... 09/15/05 - 20050202793 - Method and system for superheterodyne detection of an optical input signal A system and method for superheterodyne detection in accordance with the invention. The system comprises a first conversion unit for performing a first heterodyne operation on an optical input signal to generate an electrical IF signal. A second conversion unit is electrically or optically coupled to the first conversion unit. ... 09/08/05 - 20050197084 - Mixer circuit and receiver circuit using the same A mixer circuit is provided with a quadrature demodulator including a Gilbert cell in which a first differential amplifier and a switching circuit are vertically stacked for connection and a bypass circuit including a second differential amplifier having a pair of differential input terminals short-circuited with each other, and provided ... ### FreshPatents.com Support |
