A microwave radio terminal capable of multiple gigabits/sec bit rate is provided. The radio terminal may use QAM modulation, including the two lowest modulation formats of BPSK and QPSK. The serial bit stream, including forward error correction (FEC) and all other overhead, is prepared in a digital circuit, such as a filed programmable gate array (FPGA) and is output serially, using SERDES devices inside the FPGA, as two separate channels known as “I-channel” and “Q-channel”.

An actuator that has two or more degrees of freedom that moves a payload are described. The actuator may have two members, an actuator stator and an actuator armature, with the ability to move relative to each other in two or more degrees of freedom.
摘要:
A tunable element in the microwave frequency range is described that may include one or more tunable elements that are directly digitally controlled by a digital bus connecting a digital control circuit to each controlled element. In particular, each digital signal is filtered by a digital isolation technique so that the signal reaches the tunable elements with very low noise. The low noise digital signals are then converted to analog control voltages. The direct D/A conversion is accomplished by a special D/A converter which is manufactured as an integral part of a substrate. This D/A converter in accordance with the invention may consist of a resistor ladder or a directly digitally controlled capacitor. The direct digitally controlled capacitor may be a cantilevered type capacitor having multiple separate electrodes or sub-plates representing binary bits that may be used to control the capacitor. A low cost microwave oscillator is disclosed in which some of the filters and oscillators are direct digitally tuned elements.

A method of multiplexing multiple terminals in a distributed network includes transporting user traffic and telephony signaling information. Transporting user traffic includes converting the user traffic into ATM cells, passing the ATM cells over a wireless link to a TDM port in an ATM multiplexer wherein the ATM multiplexer includes an ATM circuit emulation service, and converting the ATM cells into user traffic. Transporting telephony signaling information includes extracting the telephony signaling information from a user interface, passing the telephony signaling information to a base station using an ATM virtual circuit, processing and aggregating a number of telephony signaling information into a single channel, and transmitting the single channel to the ATM multiplexer.
