Since
1953, North Hills has provided precision leading edge RF components
to the OEM. An inherent understanding of the intricacies of high frequency magnetic
technology together with the capacity to meet or exceed difficult design parameters
has given North Hills an industry-wide reputation for providing high-quality
magnetic devices with superior performance characteristics. World-class
manufacturing facilities, processes, field experience and pride
in workmanship bear testimony to the Company's long success..
Wideband Transformers:
Wideband transformers match impedances for maximum power transfer or convert
single-ended signals to a balance configuration (balun) for transmission of
communication signals. Baluns have low transmission loss and superior return
loss. See Application Note 159 to learn more about baluns. A wide selection
of balanced to unbalanced (Baluns) and unbalanced to unbalanced
(Ununs) designs in the 20Hz – 300MHz frequency range are available.
Wideband Instrumentation
Devices:
The LBB series, Longitudinal Balance Bridges, facilitate the measurement
of balance, Longitudinal Conversion Loss (LCL) and Longitudinal Transverse Conversion
Loss (LTCL) per ITU-T Recommendation O.9. The RLB, RLC, and RLT series of Return
Loss Bridges are used to measure the impedances of various devices and networks.
Both product lines are designed for use with 50 or 75 ohm network analyzers.
See the appropriate data sheet and application notes to find the suitable
devices for your application.
Video Isolation: “Humstoppers” and “Humbuckers ” prevent interference
with video and data transmission due to pickup and potential differences between
remote grounds. If picture quality is an issue, check out North Hills DC-isolated "Humstoppers" for
power-line isolation and DC-coupled "Humbuckers" for common mode noise
elimination.
North Hills now manufactures RoHS compliant versions of our Wideband Transformers.
To order a RoHS compliant Wideband Transformer simply add the letters LF at the
end of the model number. For example: North Hills balun transformer 0300BB-LF
is a RoHS compliant product.
