H-MODE HIGH LEVEL SWITCHING MIXERS FOR HF WITH FST3125M IC |
IT CAN ACHIEVE AN OUTSTANDING IIP3(input IP3) around
+40dBm to + 42dBm equal to an OIP3 (output) of +35 to +37 dBm with 5dB of insertion
loss in the HF range and IF
at 9MHz (for input signals level range up to +5dBm). Isolation between ports is good
and OL power required is around 0 dBm and +5dBm much less than for passive high
level diode mixers. DO NOT LEAVE Floating the LO input when powering ON
the board. With AC SOIC IC logic Total Power Supply Current, with LO generator connected with signal at 0 dBm, is around 22 mA at 5,000 Volt. |
