Post by thread:[EE]: RF amp (was: Bouncing messages)

> Stability? (Will output always see 50 +j0, built-in VSWR protect, etc) Needs to withstand stupid user tricks (no antenna, bent antenna, etc) - high VSWR possible. > BW? (1 MHz, 10 MHz) Not picky, xmitter will be fixed at 174.2xx MHz. > Efficiency? While powered by 13.8V, it's not critical. On battery it's a little more so, but transmissions would be very short (< 300ms) and intermittent. > Temp range? Outdoor use... say -20 to +40 C > Expected life-time? Good question. Forever, if you ask the end user. 3-5 years minimum. It'll be potted, but the case can be used as a heat sink. Dale -- http://www.piclist.com#nomail Going offline?
