Datasheet STMicroelectronics BALF-SPI2-01D3

BALF-SPI2-01D3
50 Ω nominal input / conjugate match balun to ST S2-LP,
868-927 MHz with integrated harmonic filter
Datasheet -production data Description
This device is an ultra-miniature balun. The
BALF-SPI2-01D3 integrates matching network
and harmonics filter. Matching impedance has
been customized for the ST S2-LP transceiver.
The BALF-SPI2-01D3 uses STMicroelectronics
IPD technology on non-conductive glass
substrate which optimizes RF performance.
