Manufacturer:TI Description:where R15 should be greater than 33 kΩ. Smaller values for C13 will reduce the sensitivity to RF input pulses. The MOSFET turns ON within approxi- mately 1.5 µs (shunting the RF signal to ground) after a noise pulse is detected and then turns OFF over a 15 µs period after the end of the RF gate time. The ON resistance of the MOSFET is about 30 Ω. The slow turn-OFF prevents any additional transients from being introduced into the receiver by the RF gate. The internal gate circuit also includes charge-balancing circuits so that switching transients are canceled and do not appear at the output. These features ensure transient-free switching even when the RF gate is connected to the low-level input stages of a receiver. Note that the RF gate must be connected to a supply to obtain the minimum ON-resistance of the MOSFET gate. This makes it convenient to connect the RF gate in parallel with the receiver mixer output transformer primary. |
