Walsin RF Devices

Walsin RF Devices includes multilayer ceramic (MLCC) bandpass, lowpass filters, and diplexers designed for a wide range of RF applications. The MLCC bandpass and lowpass filters feature low profile thickness, low insertion loss, and a low-temperature co-fired ceramic (LTCC) process. The MLCC filters are available in the  RFBPF, RFLPF, and RBBPF series. The Walsin RF Devices lineup also includes RFDIP series diplexers, which are designed to operate multiple transmitters on a single RF antenna. The RFDIP multilayer ceramic diplexers feature low insertion loss and the LTCC process.

RFBPF Bandpass Filters
This series offers a frequency range between 2400MHz and 2500MHz. These bandpass filters are used in BLUETOOTH®, 2.4GHz ISM band RF, wireless LAN 802.11b/g/n, and HomeRF applications.

RFLPF Lowpass Filters
The RFLPF filters operate in a 4900MHz to 5950MHz frequency range and -40°C to +85°C temperature range. These lowpass filters are used in 4900MHz to 5950MHz band RF applications, 5G wireless communication system applications, and WLAN.

RBBPF Bandpass Filters
The RBBPF Series operates at a 1125MHz to 1675MHz frequency range and -40°C to +85°C temperature range. These bandpass filters are used in DOCSIS and MoCA applications.
