RFMW Ltd. announces design and sales support for high gain, high linearity power amplifiers designed for ‘small cell’ applications. The Skyworks SKY66186-11 provides 38 dB of gain for LTE radios operating in the 728 to 768 MHz frequency range (B12, B13, B14, B17). Designed for high linearity at elevated temperatures, the SKY66186-11 supports outdoor applications where ambient temperatures range from -40 to +85 degrees C.
RFMW Ltd. announces design and sales support for a GaN power amplifier. The Qorvo QPA2237 offers 10 W of saturated output power from 30 MHz to 2.5 GHz. Small signal gain is >18.5 dB while large signal gain is >13 dB. The QPA2237 draws 360 mA from a 32 V supply with 48% power added efficiency (PAE). Serving electronic warfare (EW), radar and communications markets, the QPA2237 comes in a 4 x 4 mm, plastic overmold QFN package.
RFMW Ltd. announces design and sales support for a small cell duplexer. The Qorvo TQQ6103 BAW technology offers high isolation for LTE Band 3 uplink (1747.5 MHz) and down link (1842.5 MHz) filter requirements in base stations, repeaters, signal boosters and small cells. With full 75 MHz bandwidth, in band insertion loss is only 4.1 dB while UL/DL attenuation is 44 dB. The TQQ6103 requires no external matching and handles 29 dBm of power.
RFMW Ltd. announces design and sales support for a single-chip front end module serving battery powered or portable applications such as wireless meter reading and smart energy. The Qorvo RFFM6900 covers the 900 MHz ISM band (890 to 960 MHz) with up to 1 W of transmit power. Integrated into the FEM is a PA, SP3T antenna switch, transmit harmonic filter, transmit through path, LNA with bypass mode and matching components for 50 ohm I/O.
RFMW Ltd. announces design and sales support for model QPA3240 from Qorvo. The QPA3240 supports DOCSIS 3.1 CATV amplifier designs with up to 24.5 dB gain from 45 to 1218 MHz. Superior return loss performance and extremely low distortion (CSO = -76 dBc and CTB = -73 dBc) characterize the QPA3240 which combines the advantages of both GaAs and GaN for excellent linearity and high output capability of 62 dBmV.
RFMW Ltd. announces a 1 W linear amplifier targeting small cell base stations, repeaters and boosters. Operating from 1.8 to 2.7 GHz, the Qorvo TQP9113 provides up to 30.6 dBm P1dB with >27 dB of gain. With excellent linearity, OIP3 is measured at 41 dBm. The TQP9113 draws only 215 mA from a 5 V supply and integrates inter-stage matching and input matching with a shutdown mode for a less complicated design implementation and increased link range.
RFMW Ltd. announces design and sales support for the RF circulator isolator, (RFCI) model RFCR8801 circulator. The RFCR8801 covers the full S-band (2-4GHz) in a drop-in package configuration. Broadband performance is outstanding with typical insertion loss <0.5 dB and >19 dB isolation. Forward power handling is rated at 50 W average and 500 W peak. Reverse power handling is 30 W CW.
RFMW Ltd. announces design and sales support for the API Weinschel 7006-1 DC block. The 7006-1 is an ‘inside’ DC block containing capacitance in-series with the center conductor to prevent the flow of DC current while permitting RF power to flow uninterrupted. The 7006-1 passes RF from 9 kHz to 20 GHz with an SWR of 1.3:1. API Weinschel rates the power handling at 20 W averages and 100 W peak. Maximum DC voltage is 50 V.
