1. [AMPS] 6146 high imd/receivers (score: 1): Author: irosky@yahoo.com (igor rosky); Date: Sat, 20 Feb 1999 17:45:29 -0800 (PST); Yes there appears to be some techniques that develop high thrid order IMD with solid state devices. The modern trend is to use "Feedforward rather than Feedback" Feedback being patented back in the 1; /archives//html/Amps/1999-02/msg00549.html (12,649 bytes)
2. [AMPS] 6146 high imd/receivers (score: 1): Author: dhearn@ix.netcom.com (dan hearn); Date: Sat, 20 Feb 1999 18:42:13 -0800; Igor: you say some scanners have +30 dbm IP3. Have you actually measured that? If so what was the MDS? You can increase the IP3 of any receiver by reducing the RF amp gain or even eliminating it if M; /archives//html/Amps/1999-02/msg00551.html (14,308 bytes)
3. [AMPS] 6146 high imd/receivers (score: 1): Author: irosky@yahoo.com (igor rosky); Date: Sat, 20 Feb 1999 19:16:53 -0800 (PST); No not a typical scanner, but the AOR 7030 plus, this receiver has created quite a controversy. Its 3rd order intercept point is +30dbm, for a $1500 dollar receiver is very good. It certainly blows t; /archives//html/Amps/1999-02/msg00552.html (16,374 bytes)
4. [AMPS] 6146 high imd/receivers (score: 1): Author: dhearn@ix.netcom.com (dan hearn); Date: Sat, 20 Feb 1999 22:29:34 -0800; Igor: Does the AOR 7030 plus spec give a number for MDS? Also, does it give the signal spacing used for the measurements? Most transceiver manufacturers use whatever signal spacing gives them a good; /archives//html/Amps/1999-02/msg00557.html (18,936 bytes)
5. [AMPS] 6146 high imd/receivers (score: 1): Author: Peter_Chadwick@mitel.com (Peter Chadwick); Date: Mon, 22 Feb 1999 10:33:50 -0000; A 10 dB noise figure on SSB with a +30dBm 3rd order intercept point is really good - except that you need -164dBc/Hz of phase noise averaged across the SSB bandwidth to make any use of it.
