As a local supplier focused on high-performance SAW filters, Suzhou Hangjing Elec & Tech Co., Ltd introduces the SF11S5-1575.420-F2.4IL0.9A GPS L1 Surface Acoustic Wave (SAW) filter, targeting the 1575.42MHz standard GNSS band. Its performance is comparable to mainstream international products from Murata, TDK, and Qorvo, providing stable and domestically controllable device options for positioning terminals.
1. Basic Parameters & Core Features
Low Insertion Loss
Center frequency: 1575.42MHz
Passband bandwidth: 2.4MHz
Insertion loss: 0.9dB typical, 1.3dB max
Amplitude ripple: ≤0.5dB
→ Ensures high sensitivity for positioning signal reception.
Moderate Out-of-Band Rejection
Near-end out-of-band rejection: 42–47dB
→ Effectively isolates external RF interference from LTE, 5G, etc., reducing position drift and satellite acquisition delays.
Small Standardized Package
Package size: 1.4×1.1×0.6mm – identical to Murata's same-spec product, directly compatible and replaceable. Compared to larger TDK models, it better fits compact PCB layouts in wearable and portable devices.
Standard Wide-Temperature Operation
Operating temperature range: -30°C to +85°C – covers the majority of civilian environments for in-vehicle, drone, and IoT terminal applications.
Storage temperature range: -40°C to +85°C – meets storage and low-temperature outdoor requirements.
RoHS Compliant & Green Design
RoHS lead-free compliant, with standard production and delivery processes.

All share the same center frequency, making hardware directly interchangeable.
Insertion loss (0.9dB typ) is in the mainstream range and better than some TDK series.
VSWR (1.2 typ) matches Murata and TDK.
Out-of-band rejection (42-47dB) meets anti-interference requirements for conventional civilian positioning devices.
Operating temperature suits most domestic terminal scenarios; overall performance reaches a viable replacement level.
