Advanced SAW filtering solutions for global defence, aerospace and communications markets
London, UK; 11 November 2026 – AA Frequency Solutions, exhibiting at Electronica 2026, highlights the growing importance of Surface Acoustic Wave (SAW) filtering technology across military and defence, aerospace, UAV, satellite navigation and wireless communication markets.
Increasing global investment in defence capabilities, autonomous systems, satellite infrastructure and next-generation communications is driving demand for reliable, high-performance RF filtering solutions. As electronic systems operate in increasingly complex radio frequency environments, signal selectivity, interference rejection and reliable reception are becoming essential to system performance.
GNSS SAW filters for multi-constellation navigation
Global Navigation Satellite Systems (GNSS) are fundamental to modern positioning, navigation and timing applications. GPS, Galileo, GLONASS and BeiDou are increasingly used in Unmanned Aerial Vehicles (UAVs), autonomous platforms, aerospace systems and defence navigation equipment. AA Frequency Solutions offers GNSS SAW filters supporting key satellite navigation frequencies, including:
1,575.42MHz (L1/E1): GPS and Galileo
1,176.45MHz (L5/E5a): Multi-frequency navigation
1,207.14MHz (E5b): Galileo and BeiDou
1,227.60MHz (L2): GPS
1,561.10MHz (B1I): BeiDou
1,268.52MHz (B3I): BeiDou
Approximately 1,602MHz (G1): GLONASS
SAW filters improve receiver selectivity and help suppress unwanted RF signals, supporting reliable GNSS reception in demanding environments. These capabilities are particularly important for UAV navigation, aerospace electronics and defence positioning systems.
SAW filters for advanced RF communications
The expansion of 5G infrastructure, satellite communications, connected devices and modern defence communication systems is increasing demand for advanced RF filtering technologies. SAW filters help separate desired signals from unwanted interference, supporting RF front-end performance, wireless communication modules and radio equipment. Key application frequencies include:
433MHz, 868MHz and 915MHz: ISM, telemetry and IoT
700 to 960MHz: Cellular communications and public safety
1.5 to 2.7GHz: Cellular and wireless communications
2.4GHz: Wi-Fi, Bluetooth and industrial wireless
3.3 to 3.8GHz: 5G sub-6 GHz infrastructure
5GHz and 6GHz: Advanced Wi-Fi applications
L, S, C and X bands: Specialist satellite, radar and RF applications, subject to specific product requirements
With a portfolio of nearly 700 SAW filters, AA Frequency Solutions provides extensive product coverage across multiple frequency bands and applications, helping customers identify suitable solutions for their specific design requirements.
Product availability and supply flexibility are key priorities. Most products within the portfolio are available on short lead times, helping customers reduce procurement delays and maintain production schedules. Combined with technical support, international distribution partnerships and a German logistics centre offering next-day delivery options within mainland Europe, AA Frequency Solutions provides responsive supply solutions for customers across international markets.
“Reliable frequency control and RF signal integrity are becoming increasingly important across defence, aerospace and global communications markets. We offer customers extensive product coverage, technical expertise and short lead-time availability to support their rapidly evolving requirements,” said Anke Allen, Managing Director of AA Frequency Solutions.
