... DSSS signal (ACPR, 1st Side Lobe < -30dBc, 2nd Side Lobe < -50dBc). In addition, the device includes a 2.4GHz detector which is accurate over a 15dB dynamic range within ( )1dB. Therefore, an accurate ALC function can be implemented. The ISL3984 is housed lead MLFP package well suited for PCMCIA board applications. Ordering Information TEMP o ...

... When the CMOS compatible Power Enable (PE) pin is driven low, the total supply current drops to under 50 A in, typically, 300ns. When the PE pin is driven high, the full ISL3984 output power is available in a few hundred nanoseconds. In summary, the ISL3984 RFPA provides a highly cost effective solution for the PA function by integrating many features that would require signifi ...
