PHILIPS UAA3587

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
RF front-end of less than 2.5 cm2.
Semiconductors
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 generation and enables a design area of less than 2.5 cm2 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.
Key features
• Advanced, single-package RF transceiver for GSM/GPRS/EDGE
- 30% smaller than previous best-in-class solutions
- Total RF front-end < 2.5 cm2
• Eliminates 35 external components
- Integrated Tx baluns, loop filters, decoupling capacitors
- Integrated Fractional-N RF synthesizer with AFC control
- Semi-integrated 26-MHz oscillator with integrated supply regulator
• Superior performance from optimal process technologies
- 0.25µm QUBiC4 BiCMOS for RF performance
- Passive integration for lower component count
- Flip-chip assembly shortens interconnects, reduces parasitics
• Efficient, flexible architectures
- NZIF receiver architecture
- Direct conversion upmixer transmit architecture
- Triple-output control of RF antenna switches
- Any combination of 3 out of 4 bands (850 / 900 / 1800 / 1900 MHz)
• HVQFN40 package (6 x 6 x 0.85 mm)
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.
Designed for efficiency, flexibility
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).
The SiP includes integrated Tx baluns, loop filters, and decoupling capacitors.There is an integrated Fractional-N RF synthesizer with AFC control,
as well as a semi-integrated, 26-MHz oscillator clock with integrated supply
regulator.

Innovative silicon-based structure
Each portion of the SiP is fabricated in the process technology ideally suited
to its function, so each individual die delivers the ultimate balance of performance, size, and cost.

To combine high-performance passive components with active transistors,
the UAA3587 uses the QUBiC4 BiCMOS process (0.25µm, 40/90 GHz
FT/FMAX). Less critical passive components, or components that require significant silicon area, are fabricated in Philips-proprietary Passive Integration
Technologies, which only involve back-end (and hence lower-cost) silicon
wafer processing.

Using flip-chip techniques, the active die is direct-bonded to the passive
component die, thereby eliminating the need for any mechanical or interconnect substrate.The whole assembly is then housed in a standard 40-pin
HVQFN package that measures only 36 mm2.
