Source: RF Micro Devices, Inc.
The RF2489 is a high performance CDMA dual-band/trimode
integrated LNA/mixer. The device is designed to
meet all IS-98 sensitivity, intermodulation and single-tone
requirements
The RF2489 is a high performance CDMA dual-band/trimode
integrated LNA/mixer. The device is designed to
meet all IS-98 sensitivity, intermodulation and single-tone
requirements. The operating voltage is 2.7V and is compatible
with 1.8V logic for control lines. The RF2489 integrates
the dual-band LNA/downconverters with 30dB of
gain control and TX LO buffers. Additionally, a divide-by-2
prescaler to allow the use of a single-band VCO is integrated.
The design is flexible, in that the bias currents
may be set using off-chip current reference resistors for
both the LNA and mixer blocks. The device is packaged in
a 5mmx5mm leadless plastic package.
