Ultra Small Low-Profile DC- 40GHz RF-RF Cross Over

Designed for layout simplification, this compact crossover supports a reduced layer count with a surface-mount technology (“SMT”) design. It is capable of 2W CW power handling and an insertion loss from DC-18GHz of 0.4dB and 18GHz - 40GHz of 0.8dB. Ideal for mmWave applications, its high-frequency and tiny form factor can be implemented in any location where space saving, layout efficiency, and density demand it.

0805 DC - 40GHz Ultra broadband 2 way 6dB splitter

Distinguished by its embedded resistive elements, this splitter combines small size with exceptional integration. Designed for ADC-DAC splitting or combining the analog inputs for clocking systems, signal chains, passively instead of a buffer. It has a transmission loss of 6.7dB, an estimated return loss of 18dB, and an estimated insertion loss of 0.8dB from 18GHz-40GHz, addressing broadband Analog/Digital splitting needs. It is also suitable for broad applications in Test and Measurement, and COTS Mil-Aero applications.

New Group Delay Compensator (Patented) for Doherty Amplifiers

This patented SMT component addresses the challenge of group delay differences in conventional Doherty power amplifiers (“PA”s) that utilize a hybrid coupler for signal splitting and a transmission line for combining. The main amplifier path and the peaking amplifier path experience varied group delays, leading to imperfect power combining at the band edges and restricting the overall bandwidth of the Doherty PA. By cascading this delay compensator after the hybrid coupler, designers can efficiently minimize the group delay mismatch, facilitating optimal performance across wide bandwidths. While alternative solutions like power dividers and quarter-wavelength transmission lines are available, they often present design difficulties and occupy substantial board space. This innovative delay compensator allows for flexible splitting ratios using commonly available hybrids, making it an essential addition for improving Doherty amplifier performance.

Revolutionary Very Low Loss Directional Coupler Family (Patented)

This new coupler family addresses the long-standing challenges of conventional directional couplers, which have seen little significant change over decades. Designed with modern PA needs in mind, these directional couplers feature advanced packaging and design methods that drastically reduce insertion loss in the hundredths of a dB range, all within a slim-line, low-profile package. 

Initial products will be focused on applications requiring higher power and amplifier efficiencies. The long-term target is to release families of Directional Couplers in all popular frequency bands and power levels.
