AM1227B79

Overview

The AM1227B79 is a ceramic bandpass filter manufactured by Anatech Electronics Inc., designed for RF applications. It features a center frequency of 1.227 GHz with a bandwidth of 15 MHz, covering the passband from 1219.5 MHz to 1234.5 MHz. The component operates at an impedance of 50 Ohms and utilizes a monoblock package with two pad connections. Its physical dimensions are 0.369 inches in length and 0.319 inches in width.

Feature Summary

• Designed as a ceramic bandpass filter for precise signal selection
• Optimized for GPS frequency bands with specific center frequency tuning
• Constructed in a compact monoblock package for surface mounting

Applications

• GPS receiver front-end filtering
• RF signal processing systems requiring 1.227 GHz selectivity
• Military and commercial radio frequency filter modules

Procurement Notes

Verify RoHS compliance status and lead times through authorized distributors. Confirm package compatibility and soldering requirements before integration. Ensure supply chain authenticity by sourcing from verified manufacturers or certified partners to maintain component reliability.

Selection Notes

Select this component when a fixed 1.227 GHz center frequency with 15 MHz bandwidth is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the monoblock form factor for space-constrained PCB layouts requiring robust ceramic construction.
