TRF370417: Tale signal after the fall edge

Part Number: TRF370417

Dear TI Tech support,

I bought a TRF370417 IQ modulator recently and trying to use it together with a pulse generator to gate an RF sine wave(as shown in the first attached image). But I got two weird tale signals after each pulse(second image).

The I/Q are connected to a TTL pulse generator(3.3V output), and the RF signal is generated by a signal generator. I believe the input and output RF cables are all 50Ohm so the impedance should match. Could you help me take a look at the problem?

Any help will be greatly appreciated!!
