Guerrilla RF Awarded Technology Patent For High Isolation Amplifier Circuit Architecture

Guerrilla Armor Enhances Robust, Rugged Radio Architecture and Greatly Improves Device Capability to withstand High RF Input Power without Damage

Guerrilla RF Inc., a leading provider of high performance MMICs, recently announces that the U.S. Patent and Trademark Office has issued Patent No. 8,970,296. The company’s first issued patent, expiring in 2033, prevents amplifiers from turning on in the presence of large RF input signals – leading to exceptional isolation and minimal impact to their on-state performance. Guerrilla Armor also fits in the same form factor as the company’s existing, best-in-class noise figure low noise amplifiers (LNAs), requiring no additional components and resulting in substantial cost and size savings.

“Guerrilla Armor solves a unique issue found in high speed wireless data systems, which are exploding in popularity with the rise of smart phones,” said Alan Ake, vice president of applications and technical marketing at Guerrilla RF. “This makes it especially ideal for wireless backhaul 802.11ac access points and LTE-unlicensed small cells.”

International Data Corp. expects 1.4 billion smartphones to be shipped worldwide in 2015, for a 12.2 percent year-over-year growth rate. Annual growth continues throughout IDC’s forecast with unit shipments approaching 1.9 billion in 2018, resulting in a 9.8 percent compound annual growth rate for 2014 to 2018.

About Guerrilla Armor
Several of Guerrilla RF’s LNAs incorporate Guerrilla Armor including the GRF2060, GRF2062, GRF2140 and GRF2541. A number of new products, slated for introduction in the near future, will also incorporate the company’s circuit architecture. With RF input power exceeding +15 dBm, Guerrilla RF’s LNAs maintain more than 30 dB off-state transmit-to-receive isolation in all conditions.

These LNAs are primarily designed for TDD-WiFi networks, TD-LTE 4G and TD-SCDMA. Numerous proprietary systems in wireless backhaul applications benefit from these solutions, including point-to-point and point-to-multipoint fixed wireless links. The LNAs can also be used in FDD line-ups requiring switched gain states. The technology also applies to standard transmit amplifier chains, where isolation in the presence of high RF drive is required.
