Johanson Technology News

With the development of new applications and smaller end product form-factors, Johanson Technology Inc. has developed an impedance matched filter/balun Integrated Passive Device (IPD) for Semtech’s Long Range Low Power LoRa® and LoRa Smart Home™ RF transceivers SX1261, SX1262, and LLCC68. Our p/n: 0900FM15D0039 pairs seamlessly, considerably reducing the overall PCB space utilization area, and component count. With this device, the entire front end RF matching, balun, and filter network is reduced to a single EIA 0805 (2.0mm x 1.25mm) SMT component. This device is very temperature stable, cost effective, and provides compliant FCC and ETSI regulatory emissions requirements.

Johanson Technology releases p/n: 2450BM14G0011, a small footprint (EIA 0603) front-end integrated passive device for Texas Instruments’ latest multi-protocol Bluetooth Smart, ZigBee® and 6LoWPAN CC26XX family chipsets. This component encompasses an impedance matching network, balun, and Low Pass Filter (LPF) in a small, 1.6x0.8x0.6mm SMT package that significantly reduces PCB space usage, guarantees filtering (FCC/ETSI compliance), and prevents manufacturing variability. Go to: www.johansontechnology.com/ti for the datasheet and reference design (by request).

To use a high-Q capacitor at higher frequencies, a common solution is to replace it with several capacitors that have lower values arranged in a parallel position. For example, a 30pF capacitor can be replaced with three 10pF capacitors.
At Johanson, we have the ability to use capacitors with a wider capacitance tolerance and match them. This leads to a tighter tolerance for the overall capacitance value. For instance, we can use three capacitors at 10pF with a 5% tolerance and match them to get 30pF with a 1% tolerance. The result is an increase in frequency range, while keeping the cost down. We can deliver these matched capacitors in a matched set (small and medium size capacitors), or already mounted in a capacitor assembly (large size capacitors, i.e. 2525 and 3838).

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.

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 INC. is proud to announce that we have earned ENVIRONMENTAL MANAGEMENT CERTIFICATION to ISO14001. With this achievement, JOHANSON TECHNOLOGY INC. (JTI) is recognized as meeting the highest standards set by the International Standards Organization (ISO) for both Environmental Management (per ISO14001) as well as Quality Management (per ISO9001). These achievements join JOHANSON DIELECTRICS’ certification to ISO9001 and AS9100 (Aerospace Quality Management) demonstrating our high standards and commitment to our customers, suppliers and community.

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.

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.

For location systems needing redundancy, the addition of new civilian-use signal is transmitted on a frequency other than the L1 (1.575GHz). The L2C signal is able to improve accuracy of navigation, provides an easy to track signal, and acts as a redundant signal in case of localized interference. Johanson Technology p/n: 1227AT45A0042

Due to the increasing interest in 1dBi+ gain satellite internal chip antennas that can operate in both GPS and GLONASS bands at the same time; we’ve released our new GPS/GLONASS SMD Antenna: P/N 1575AT54A0010. This antenna is compact (15x4x3.2mm) and can replace more expensive patch antennas offering similar performance in small portable applications. Samples immediately available.

Our brand new BPF has the highest close-to-passband rejection 2.45GHz BPF with the smallest footprint ever made by us in an 0805 package. It uses an LGA termination for reduced real-estate usage. This component is in full production and has no MOQ required. Great 30dB min Atten @2170MHz. Samples and EVBs immediately available.
