Could anyone out there tell me if the 2SK152 (GaAs FET) is a commercially manufactured part and if so, some details or sources? It is being used in the front end of the Sony ICF-2010 receiver and perhaps some ham rigs as well. Isn't an SKxxx part a silicon device, and is it that GaAs devices are being given the 2SKxxx id's? Thanks in advance for any information. ----------------------------------------------------------------------------- Sriram Narayan 810446 Texas A&M University | INTERNET: narayan@photon.tamu.edu | Go Alain Prost!

Typical uses are low noise head amplifiers for VTR's, and the main claim to fame is high transconductance/capacitance ratio "|Yfs|/Ciss = 3.5 (typical) at 10 mA" 15V max, 50 mA max drain voltage and current, input capacitance under 9 pF, and Ids between 9.5 and 42 mA at Vgs=0.0. The noise figure is 1.8 dB in a circuit with 15 dB gain, 50 ohm input impedance, measured near 100 MHz. Voltage input noise is 1.2 nV/sqrt(Hz) at 1 kHz with 10 mA drain current and grounded gate. Sony's Texas reps are B-P Sales, at (214) 234-8438, or (713) 782-4144, or (512) 346-9186, as well as Shefler-Kahn (in El Paso county), (505) 345-3591. And Marshall Industries is listed as a distributor in your neck of the woods. Lookit all those different area codes! Texas must be BIG! I am known for my brilliance, John Whitmore by those who do not know me well.
