Cable TV Receiver 1GHz High Rejection STB Filter
Johanson releases new 1GHz STB (Set Top Box), MoCA reject low pass filter designed for 75ohm systems. Newer home networking technologies always present opportunities and challenges and CATV various frequencies coexistence is no different, especially with systems using less and less wires. Johanson has released 75Ohm 1GHz LPF p/n: 1000LP41B1000 in mass production to help solve these design predicaments.
New 100V GBBL SLCs for Optical Modules
Extended range Receive Optical Sub-Assemblies (ROSAs) for fiber optic network systems require high sensitivity Avalanche Photo-Diode (APD) detectors instead of the standard PIN-diode detector. To improve detector sensitivity, the bias to an APD must have a high capacitance broadband filter on the power input to the device. This filter prevents high-frequency noise getting to the APD via the power input and interfering with the incoming signal. JTI SLCs using our GBBL dielectric fit the capacitance and broadband requirements for PIN-diode detector input power filtering and the VCC filtering for the associated signal processor. With the 63V and 100V ratings now available, GBBL capacitors can now also be used for the input power filtering on an APD device. Production volumes are shipping and samples are available from stock.

Johanson Technology Releases Optimized LNB Diplexers:
Facing challenges of IF signal reliability, false switching and circuit complexity, JTI has developed high rejection and optimized isolation diplexers for Low Noise Block (LNB) allowing the system design to use a smaller footprint and be more cost effective. p/n: 1175DP41B1925 and 1175DP41A1925
New High Rejection 1.4GHz Band Pass Filter
This compact SMD filter was developed with “easy RF” in mind and provide passive >35dB attenuation levels very close to passband without compromising insertion loss. The recommended application is MoCA D-Band. This cost effective filter was designed to use a small effective footprint and easily matched to 75ohm systems.
