UAA3587 RF SiP
Complete, single-package
GSM/GPRS/EDGE RF transceiver
Integrating passive and active components into a single
package, this complete RF transceiver improves performance
while eliminating 35 external components and enabling an
2
RF front-end of less than 2.5 cm .
S e m i c o n d u c t o r s
The UAA3587, the first Philips System-in-Package (SiP) solution to use a
new silicon-based structure, is a complete RF transceiver for GSM, GPRS,
and EDGE mobile phones. It uses innovative techniques to combine passive
and active components in a single package, maximizing RF performance
while significantly reducing external component count and overall design size.
The SiP uses 35 fewer external RF components than the previous genera-
2
tion and enables a design area of less than 2.5 cm for the complete radio
sub-system. Combined with the miniaturization of other components, the
SiP offers increased RF performance while saving 30% more space than the
previous “best-in-class” solution and 50% more than the industry average.
By replacing dozens of active and passive components in a single, drop-in
solution, the SiP dramatically cuts assembly costs and time-to-market. By
bringing the passive component networks closer together, the SiP shortens
interconnect lengths and reduces parasitics, thereby improving overall RF
performance.
Key features
• Advanced, single-package RF transceiver for GSM/GPRS/EDGE
Designed for efficiency, flexibility
- 30% smaller than previous best-in-class solutions
The receiver uses a Near Zero-IF (NZIF) architecture.The transmitter uses
a direct-conversion upmixer architecture that delivers -163 dBm/Hz at 20 MHz,
a carrier rejection of greater than 35 dB, and a transmit attenuation range of
40 dB. The RF antenna switches can be controlled by up to three outputs
and the transceiver as a whole can support any combination of 3 out of
4 GSM/GPRS/EDGE bands (850 / 900 / 1800 / 1900 MHz).
