1N270 are RF optimized Germanium diodes, not hot carrier diodes.
1N5711 are passivated Schottky barrier diodes an,d as Frank points out, offer superior RF performance. -Ray WB6TPU ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of FRANCIS CARCIA Sent: Thursday, February 07, 2008 7:48 AM To: [email protected] Subject: Re: [soft_radio] Diodes as mixers? 1N270s are not that good and fairly high leakage try 1N5711 Daniel Jackson <[EMAIL PROTECTED]> wrote: I am using 1N270 hot carrier diodes which are more sensitive than the past, small signal diodes, in QSD mixer designs. I borrowed the idea from the SPL-1 and TUF-1 mixers.
