Hi to all,
first of all great forum i never
heard about before
i'm looking for RF ac
switch w next specificatin (a bit flexible):
i would be glad if someone will be able to help
me find such
- Operation frequencies: 0-20MHz
- SPST or SPDT
- Application: pass around
6W in Lo freq, block around 10mW in Hi freq
- Close/on state (when around 3Vdc applied to
the switch controls):
Can pass 6Watt, 25Vac peak2peak
@ < 0.5MHz (signal freq)
- Rds on: up
to 200mOhm when switch is on state for minimal loss
- Open/off state (when no power applied to the
switch):
Can block 25Vac peak2peak @ above 10MHz
signal , w isolation around 20dB
as if Hi freq
signal sees 10Kohm resister.
- Low profile:
SMT part, preferably around 1mm height
-
Target price: up to 2$ per unit
- i emphasise
that there isn't DC supply i'm plannig to use the
ac Lo freq 25Vac peak to peak for the control signal
by using a bridge or a diode.and when Hi freq is
in the source i plan to use no DC power at all.
i'm looking for such a long time w no sucsses
:-( would be glad if someone could advice me or
even declare that there is no solution
Tnx
