General Description and Notes for CMY 81
CMY 81 is a general purpose down-converter device designed for multiple applications
such as cellular mobile phones, ISM bands, and pagers. Due to its excellent
intermodulation characteristics and its low current consumption, CMY 81 is particularly
suited for CDMA receiver applications.
The device combines an RF amplifier with variable gain and an ultra-linear mixer with
2 LO - driver stages in a very small P-TSSOP-10-2 package. The input and output
matching of the RF amplifier can be adapted externally within a frequency range from
600 to 1000 MHz.
The mixer section of CMY 81 combines low conversion losses and excellent
intermodulation characteristics with low LO- and DC-power demand. The internal level
controlled LO-Buffer enables a good performance over a wide LO level range. If higher
input LO power is available, the first LO amplifying stage can optionally be bypassed by
inserting the LO signal at pin 3 instead of pin 2, resulting in a reduced current
consumption of 2.5 mA. The mixer’s principle with a common RF and IF port requires a
frequency seperation at pin 7.
An integrated negative voltage generator allows to operate the device with one positive
supply voltage. The operating current of the entire MMIC is typically 10 mA, but can be
adjusted to lower and higher values by an external resistor, resulting in less and more
gain, respectively.
