748MHz VCO
This fully integrated VCO does not require external elements
such as inductors and varactors. Load pull rejection is
excellent, eliminating the need for an external buffer
amplifier. A differential design provides inherent rejection of
spurious signals which simplifies the PCB layout.
The ISL3183 is housed in a 16 lead QFN package well
suited for PCMCIA board applications.
