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.

Highly reliable actuator with multiple degrees of freedom and method for moving a payload using the actuator

A communications system are provided that provides integrated encryption capabilities. In particular, a digital microwave system, terminal and method are provided in which the encryption functions are integrated into the digital microwave terminals. The digital microwave system may also be implemented with external encryption units.

Digital microwave radio system and method with encryption

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'.

Digital microwave radio link with a variety of ports

A digital microwave link and system are provided that has an adaptive data rate.

A high frequency device packaging method is described wherein an insulating material, attached to a fiat surface, is selectively etched and the etched insulating material is plated with a conductive material to form a center conductor for a coaxial via structure.

Process of manufacturing high frequency device packages

A system and method for communicating signals over a noisy channel is provided wherein an input signal may be sampled and modulated to make the signal more noise insensitive. In accordance with one embodiment, of the invention, an signal code modulation (SCM) scheme may be used wherein digital and analog signals representing the original signal are generated. In another embodiment, an original modulated signal may be demodulated and then remodulated using a more robust modulation scheme. The system may be used to a variety of applications including wireless internet access.

Signal communications system and method for noisy links

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.
