RF & Wireless Components High-Q Tunable Inductors RFMW, Ltd. announces design and sales support for the 5SQ series of Tunable Inductors from Frontier Electronics. The 5SQ series offers the highest Q in the industry (Q = 100 for the 5SQ-08). Low insertion loss minimizes roll-off near the cut-off frequency in low-pass, high-pass and band-pass filter applications. Diplexer designs benefit from the low insertion loss as well and experience very good stability over temperature. Additional applications include tuner circuits and oscillators. The 5SQ series tunable inductors have an impressive reliability history with zero field failures among the 50 million pieces already shipped by Frontier Electronics. Inductance ranges from 0.0275 µH (5SQ-01A) to 0.53 µH (5SQ-09) with selfresonant frequencies from 450 to 1450 MHz. Frontier Electronics 5SQ series tunable inductors are all RoHS compliant. ■ RFMW, Ltd. info@rfmw.com www.rfmw.com Five New Power Amplifiers for Small Cell Applications Richardson RFPD announced the availability and full design support capabilities for five new power amplifiers for small cell applications from Skyworks Solutions, Inc.

The MMRF5014H is a 125 W continuous wave GaN on SiC transi- Guerrilla RF Inc. introduced the newest members to the company’s family of 5 GHz ultra low noise amplifier/linear power amplifier drivers. These new devices feature best-in-class noise figure (NF), gain and linearity. The cost-effective, small footprint, flat-gain solutions are designed for WLAN access points offering the highest levels of performance for demanding 802.11ac applications. Infonetics Research expects the WLAN equipment market to accelerate in 2015 as spending by service providers and education increases and 802.11ac reaches critical mass. The GRF2505 features ultra-low noise and high linearity over the 5 to 6 GHz band making it ideal as either an LNA or as a power amplifier (PA) driver for demanding 802.11ac applications. The strict linearity requirements often demand a high performance driver between the transceiver output and the input to the final PA and the GRF2505, with its high IP3 and compression point, fills this role perfectly. As an LNA, the GRF2505’s ultra-low NF of 0.8 dB and high input-referenced linearity contribute to both maximum receiver sensitivity and linearity. The GRF2541 (internally matched to 50 ohms) ultra-low noise amplifier with bypass designed for IEEE 802.11 a/n/ac/p applications, 15 dB flat gain and 1.0 dB NF across the entire 4.9 to 6.0 GHz band, builds on the industry-leading gain and ultra-low NF of the previously announced GRF2501 by adding bypass-mode functionality. This bypass capability improves the receiver dynamic range for improved data rates in high signal strength environments. Guerrilla Armor technology also provides exceptional off-state isolation in the presence of high RF input signal levels in LNA power-down mode. Both the GRF2505 and GRF2541 feature adjustable bias current and Vdd, which allows for optimal application flexibility and efficiency. ■ Guerrilla RF, Inc. www.guerrilla-rf.com hf-praxis 5/2015 59
