High Frequency Ceramic Solutions Date: 06/04/2014 Application Note: AN020 M.Carmona/I.Johnson Application Note for Nordic Semi's nRF51822-QFAA, nRF51422-QFAA, nRF51822-QFAB, nRF51422-QFAB, nRF51822-QFAC, and nRF51422-QFAC Integrated RF Front End Solution Using Johanson's 1.6x0.8mm Impedance Matched Balun Filter (BPF) 2.1mm Abstract The nRF51822 and nRF51422 devices from Nordic Semiconductor are powerful, highly flexible, multiprotocol SoCs designed for Bluetooth® low energy, ANT, and 2.4 GHz ultralow power wireless applications. The devices are built around an ARM® Cortex™ CPU and integrate fully compliant Bluetooth low energy and ANT stacks. The devices also include a rich selection of analog and digital peripherals such as ADC, serial interfaces, PWM, and quadrature demodulator - that can be used in a wide range of ultra-low power applications. This application note describes how to use Johanson Technology’s 2450BM14E0003 balun-filter, shares active measured results obtained with the chipsets, provides design files for ease of use on any PCB/Application environment and RF technical support contact info at Johanson Technology. 0.52mm Introduction In partnership with Nordic Semiconductor, Johanson Technology has developed an 6-pin EIA 0603 (1.6mmx0.8mmx0.7mm) ceramic passive device that contains the following functions: -Differential complex impedance (X+jY) matching network for the nRF51822 and nRF51422 -Differential to 50Ω single-ended balun -Specifically designed BPF to pair with the nRF chipsets for FCC/ETC (+Korea, Japan, China) emissions compliance This front-end 6-pin device considerably reduces implementation size area by using smaller effective PCB real estate usage. Also, it reduces component count, eliminates RF variability (100% RF tested before T&R), and offers excellent temperature stability (4ppm). AEC-Q200 available.
