Ferrites solve EMC at the board level
The Ferronics 24-0EMI/RFI kit is a ferrite kit which solve a wide range of EMI/RFI problems.
The HMC247 is a 5 to 18GHz analogue phase shifter die which provides a continuously variable phase shift of 0 to 450 degrees at 5GHz, and 0 to 100 degrees at 18GHz.
The phase shift is monotonic, and controlled by a single analogue DC voltage from 0 to +10V.
Insertion loss is less than 4dB and is very consistent versus control voltage.
The HMC247 die is compatible with standard epoxy die attach techniques and ball or wedge wirebonding.
For surface mount applications, the HMC538LP4 6 to 15GHz analogue phase shifter is housed in a leadless QFN 4 x 4mm SMT package, and provides a variable phase shift of 0 to 750 degrees at 6GHz, and 0 to 450 degrees at 15GHz.
The HMC538LP4 is controlled by a single positive voltage from 0 to +5V, and accepts a modulation bandwidth of up to 50MHz.
A RoHS compliant version is also available as the HMC538LP4E.
For test equipment and instrumentation applications where robust packaging is required, the HMC-C010 6 to 15GHz analogue phase shifter module offers the same outstanding wideband performance as the HMC538LP4, and is housed in a miniature, hermetically sealed module with removable SMA connectors.
The HMC-C010 is rated for operation over the -55 to +85C temperature range.
These phase shifters are particularly useful for adjusting the phase of clocks in fibre optic systems and test equipment, and in antenna beam-shaping and signal cancellation applications.
