1.9GHz DECT NR+ Antenna & Band Pass Filter

Compact RF Passive Components for DECT-2020 NR+, Legacy DECT, and Wireless Systems
Johanson Technology, a global leader in high-performance RF ceramic components, has introduced a compact and highly optimized RF front-end solution for 1.9 GHz DECT NR+, DECT-2020 NR, and DECT 6.0 wireless voice applications.
This solution features two precision surface-mount RF components designed to work seamlessly together:
- P/N 1905AT45A0050001E – a miniature ceramic chip antenna
- P/N 1905BP18A0050001E – a high-performance band pass filter
Together, these components form a matched antenna-filter pair optimized for the 1880–1930 MHz band, offering:
- Long-term RF stability using LTCC and high-Q ceramic filtering technology
- Excellent out-of-band signal rejection and impedance matching
- High radiation efficiency in space-constrained wireless designs
- Simplified PCB layout and improved reliability for DECT modules
This compact solution is ideal for embedded DECT wireless modules, low-power voice systems, and smart home applications, where signal clarity, board space, and power efficiency are critical.
Optimized for 1.9 GHz Wireless DECT Product Integration:
Wireless systems in the 1.9 GHz band require robust components that perform well under layout constraints and mechanical stress. This matched pair delivers exactly that:
P/N 1905AT45A0050001E – Ceramic Chip Antenna
- 2.5 dBi peak gain
- 78% average efficiency
- High detuning resistance in tight or plastic enclosures
P/N 1905BP18A0050001E – Bandpass Filter
- ≤ 1.65 dB insertion loss
- ≥ 30 dB attenuation at 2.4 GHz and 5.6 GHz
- Ideal for coexistence with WiFi, Bluetooth, and LTE signals
This pairing simplifies FCC, CE, and ETSI compliance—helping engineers accelerate time-to-market with confidence in spectral performance.
Applications for 1.9 GHz DECT and RF Voice Modules:
These components are optimized for a wide range of DECT-based and 1.9 GHz RF designs, including:
- DECT NR+ voice and data modules
- DECT-2020 NR IoT gateways and smart sensors
- DECT 6.0 cordless phones and base stations
- Smart home DECT access points and voice hubs
- Wireless healthcare monitoring systems
- Cordless VoIP handsets and DECT intercoms
- Factory automation controllers with RF connectivity
- Environmental monitoring sensors using DECT
DECT NR+ & DECT Product Types:
These components have been successfully integrated or are ideally suited for the following DECT-based product categories:
- DECT NR+ base stations for residential and enterprise voice
- Smart home automation hubs using DECT-2020 NR for secure backhaul
- Industrial IoT controllers and actuators using DECT NR+
- Medical monitoring devices with DECT for HIPAA-compliant wireless transmission
- Cordless DECT 6.0 phones in consumer and enterprise systems
- Secure building access systems using DECT for voice confirmation
- Wireless intercoms and door entry modules with 1.9 GHz RF
- Factory floor condition monitoring using DECT NR+ sensors
- IoT-enabled environmental monitors leveraging DECT-2020 NR
These applications benefit from the antenna’s mechanical flexibility and the filter’s ability to maintain clean spectral performance across changing operating environments and RF congestion.
