摘要： A controllable-gain circuit (TI, Rt, TS1, . . . , TS4) provides a first and a second pair of complementary gain-controlled signals (Ip1, Ip3; Ip2, Ip4) in response to an input signal (RFI). In each pair, one gain-controlled signal (Ip1, Ip2) is the input signal amplified with a gain G comprised in a range between a minimum gain Gmin and a maximum gain Gmax. The other gain-controlled signal (Ip3, Ip4) is the input signal amplified with complementary gain Gmax-G. A fixed-gain output circuit (Rfg, Nfg) makes a weighed sum (Ip1*Rfg+Ip3*Rfg) of one and the other gain-controlled signal in the first pair of complementary gain-controlled signals. The respective weighing factors for one and the other gain-controlled signal are substantially similar (Rfg). A controllable-gain output circuit (Rlg, Rhg, Nlg, Nhg) makes a weighed sum (Ip2*Rlg+Ip4*(Rlg+Rhg)) of one and the other gaincontrolled signal in the second pair of complementary gain-controlled signals. The respective weighing factors for one and the other gain-controlled signal are substantially different (Rlg, Rlg+Rhg).

摘要： Structure and design methods of electrical power amplifiers suitable for broadband application such as television frequency or white spaces. An example broadband power amplifier passes a transmit carrier with modulations from BPSK to 256 QAM, on channel bandwidths from 6 to 32 MHz, over the entire UHF television band from 470 to 800 MHz using a low voltage, low power, narrowband power amplifier transistor. Based on a push-pull technique to lower the impedance level thus improving the match and doubling the power, the wide-band power amplification is performed with a balanced polynomial filter transform structure wherein the circuit impedance increases sequentially within the filter stage. The polynomial filtering makes high selectivity of out-of-band signals thereby cleaning up harmonic signals which prevent the need for additional high selective radio frequency filters. The invented power amplifier enables efficient broadband power amplifiers having a form factor within 300 square millimeters of space.

摘要： A system and method provide adaptive filtering of radio frequency (RF) signals. Multiple signals are received in a predetermined RF spectrum, the signals including a desired signal and multiple potentially interfering signals. A first signal of the potentially interfering signals is down-converted to a baseband signal, and a power of the baseband signal is determined. When the power exceeds a predetermined threshold power, a first notch filter, corresponding to a frequency of the first signal, is activated.
