| 7369837 | Frequency-mixing method and frequency-mixing device using the same A frequency-mixing method includes a step of generating a first quadrature signal having a predetermined frequency, a second quadrature signal having a phase difference of about 180 degrees with respect to a phase of the first quadrature signal, a third quadrature s... | 05/06/2008 |
| 7356318 | Quadrature subharmonic mixer A quadrature subharmonic mixer comprises a polyphase filter configured to generate quadrature components of a local oscillator (LO) reference signal, a summing and scaling element configured to create additional components of the LO reference signal, and a plurality... | 04/08/2008 |
| 7319716 | Transmitter image suppression in TDD transceivers In a transceiver comprising a time-division-duplex (TDD) of transmit and receive functions, the characteristics of unwanted image signal energy being transmitted from the transceiver are determined, and thereafter feedback is provided to the transmitter to reduce th... | 01/15/2008 |
| 7058421 | Wireless terminal operating under an aggregate transmit power limit using multiple modems having fixed individual transmit power limits A mobile wireless terminal (MWT) includes multiple wireless modems. The multiple modems have their respective transmit outputs combined to produce an aggregate transmit output. The multiple modems can concurrently transmit data in a reverse link direction and receiv... | 06/06/2006 |
| 5920810 | Multiplier and method for mixing signals A multiplier (10) includes a transconductor (14) and a multiplier core (34). The transconductor (14) converts an RF voltage signal to an RF current signal. The RF current signal modulates the quiescent currents flowing in current conducting elements (23, ... | 07/06/1999 |
