DESCRIPTION
DLI’s surface mount catalog band pass filters utilize DLI ’s low loss temperature stable materials which offer small size and minimal performance variation over temperature. The catalog BPF ’s are offered in a variety of frequency bands, which offers a drop in solution with highly repeatable performance.
FEATURES
- Small Size
- Fully Shielded Component
- Solder Surface Mount Package
- Moisture Sensitivity Level: MSL1
- Frequency Stable over Temperature
- Operating & Storage Temp: -55˚C to +125˚C
- Characteristic Impedance: 50Ω Packaging and Ordering Information: To request tape and reel packaging, please order part number B138LA2S-T, see additional data on page 5. SPECIFICATIONS* *Electrical specifications based on typical probed performance at room temperature. Insertion loss shall vary ±0.5dB over temperature. Power rating assumes the component will be mounted to a PCB with good thermally conducting ground vias as outlined in the recommended PCB layout that are connected to an adequate heat sink. Max power is based on 125°C base temperature. Parameter Frequency Range (GHz) Min Typ.
