UMS Announces New Power Amplifiers for 5G and Space Applications

first_imgUMS, a European leader for RF & millimeter-wave GaAs and GaN products and solutions, has enhanced its portfolio with a new GaN Medium Power Amplifier (CHA6710-FAB) in surface-mount hermetic package compatible with space requirements and a Low-Noise Amplifier (CHA2595-QDG) in a low cost 4×4 mm2 QFN plastic package.Medium Power Amplifier (CHA6710-FAB)The CHA6710-FAB operates over a frequency range from 8 to 12.75 GHz and is designed in particular for X-Band radar and space Ku downlink communication systems. It exhibits 5W of saturated output power, 35% Power Added Efficiency (PAE), and 22.5 dB linear gain. This circuit is designed on a UMS proprietary space evaluated 0.25 μm GaN HEMT process. This product is also available as a bare die (CHA6710-99F).Product Summary:Frequency range: 8-12.75 GHz Linear gain: 22.5 dB Saturated Output Power: 5 W Associated Power Added Efficiency: 35% DC bias: [email protected] 0.2A 6x6mm2 hermetic metal-ceramic package Low-Noise Amplifier (CHA2595-QDG)The CHA2595-QDG operates at a frequency from 27.5 to 43.5 GHz and exhibits very low noise @ 2.3dB and low consumption at [email protected] The CHA2595-QDG is recommended for applications such as 5G MIMO antenna, 28/32/38/42GHz radio links, SATCOM links, radar receivers and test instrumentation. This circuit is designed on a UMS proprietary space evaluated 0.10 μm GaAs very low noise pHEMT process.Product Summary: Frequency range: 27.5-43.5GHz Linear gain: 19.5dB Noise Figure: 2.3dB P1dB: 11dBm OIP3: >20dBm DC bias: [email protected] 61mA 4x4mm2 QFN plastic package Click here to read more about the wideband LNA (CHA2595-QDG).Click here to read more about the GaN MPA (CHA6710-FAB).last_img read more

LaFollette Eye Clinic celebrates 30 years

first_imgLaFollette Eye Clinic is hosting several activities to celebrate it’s 30th anniversary and patient appreciation week this week.Last week, The Campbell County Artist Association brought in pieces to create an art gallery for the celebration. A giant balloon sculpture is in the lobby with props for visitors to take pictures with and join in the celebration.This week frames and lenses are 30 percent off (restrictions apply, see staff for details).Jake Riggs stands beside some of the artwork on display at LECIn keeping with the era when the clinic began, 80’s music will play all week inside the LEC.Daily giveaways will also happen. A “then and now” board is displayed at the clinic for patients to view as they wait.LEC is located on the four lane in LaFollette at the Weir Woods turn-in.  (WLAF NEWS PUBLISHED – 10/18/2018-6AM)Share this:FacebookTwitterlast_img read more
