Can a Mini-Circuits TUF-3 be substituted for a Mini-Circuits SBL-1 in a SSB circuit for 40 meters? The TUF-3 is a 4-pin design and the SBL-1 is an 8-pin design, so it requires a different socket. Otherwise, the gain, operating frequency range, isolation levels, voltage, amperage and schematic appear to be equally suitable for 7 MHz processing. Is there an impedance issue, or something else, that prevents the use of the TUF-3 in place of the SBL-1 in the design (MicroR2)? |

The data sheet minimum LO isolation is just 30 dB--there could be issues with excessive carrier leakage--the only practical way to find out is to build one and measure it. Zack W1VT ARRL Senior Lab Engineer |
