Johanson Technology nRF51822 and nRF51422 Front-End Passive

Johanson Technology nRF51822 and nRF51422 Front-End Passive is a 6-pin EIA 0603 ceramic passive device for the Nordic Semiconductor nRF51822 and nRF51422 System on Chip devices (QFN versions). This Johanson front-end passive contains an embedded, specifically designed Band Pass Filter (BPF) to pair with the nRF chipsets for FCC/ETC (+Korea, Japan, China) emissions compliance. This device considerably reduces implementation size area, eliminates RF variability (100% RF tested before T&R), and offers excellent temperature stability (4ppm).

Johanson Technology SMD RF Couplers and Hybrids

Johanson Technology LTCC directional and 90deg 3dB Hybrid Couplers offer different schemes of coupling (i.e. 10, 15, 20 dB coupling specs), maintaining ultra-low losses, signal integrity, and temperature stability.

Johanson Technology Band/High/Low Pass Filters

Johanson Technology LTCC Filters use ultra-low loss electrode materials to design and manufacture cost-effective passive ceramic filters for RF applications. These materials found in Johanson's LTCC Filters allow miniaturization of the filters while maintaining industry-leading performance and preservation of battery life for wireless applications.

Johanson Technology Diplexers

Johanson Technology LTCC Diplexers offer passive RF signal split-and-filter solutions for cellular, ISM, WiFi, and WLAN applications in standard EIA SMD packages. The LTCC Diplexers from Johanson also feature multiple filtering schemes for the signal filtering portion in order to meet the user's emission, sensitivity, and isolation needs.

Johanson Technology Chip Antennas

Johanson Technology LTCC Chip Antennas offer SMD manufacturability and high gain performance in small form-factor designs and applications such as BLE, Zigbee, ISM, and WLAN when compared to other monopole antenna design solutions. The RF resonance in the LTCC chip antennas from Johanson are 100% tested and guaranteed, providing great reliability and versatility while maintaining industry demanding performance. These antennas are easy to tune to any unique PCB environment.

Balun Filter Combos

Johanson Technology LTCC technology combines differential to single-ended RF Baluns and embeds LPF/BPFs into a cost-effective small and compact EIA package. This combining of Johanson's RF Baluns and LPF/BPFs results in a significant reduction in component count and variation during the production process while the desired high radio performance is still achieved.

Johanson Technology RF Baluns

Johanson Technology RF Baluns Transformers offer a variety of differential impedances that meet specific balanced impedance needs. The differential to single-ended RF Baluns (etymology: BALanced/UNbalanced) Transformers from Johanson are LTCC-based components that offer high temperature (+/-4PPM) stability and reliability.

Johanson Technology 2.4GHz High Rejection Band Pass Filter

Johanson Technology 2.4GHz High Rejection Band Pass Filter features LGA terminations for reduced PCB area usage, EIA 0805 footprint, highest close-to-pass band rejection, and great 30dB min attenuation @ 2170MHz.

Johanson Technology RF Ceramic Chip Inductors

Johanson Technology RF Ceramic Chip Inductors are high-frequency multilayer inductors that have a monolithic body made of low loss ceramic and high conductivity metal electrodes that result in optimal high frequency performance. The compact RF Ceramic Chip Inductors from Johanson are constructed with lead-free tin plated nickel barrier terminations and tape and reel packaging, making them ideal for small size/high volume wireless applications.  These inductors are available in case sizes 0201, 0402, and 0603, and offer inductance range from 0.6nH to 220nH.

Johanson Technology RF Proto-Typing Kits

Johanson Technology RF Proto-Typing Kits provide a wide range of high-frequency ceramic components that suit a variety of RF design needs. The RF Proto-Typing Kits available from Johanson include capacitor and inductor, non-magnetic capacitor, tuning capacitor, single layer capacitor, wirewound inductor, and more.

Johanson Technology Multilayer High Q Capacitors

Johanson Technology Multilayer High-Q Capacitors were designed for high Q and microwave applications. The S Series High-Q capacitors from Johanson offer ultra high Q performance and NPO temperature characteristics. The L Series High-Q capacitors offer mid-high Q performance and NPO temperature characteristics.
