es within the SiP housing and between
the circuit interconnections made to the
SiP package leads. The choice of PCB substrate
material and its key parameters,
such as dielectric constant (Dk) and dissipation
factor (Df) or loss, contributes
strongly to achieving desired SI levels
especially in high-frequency, high-speed
mixed-signal SiPs with closely spaced
package interconnections.
High-density SiPs often require PCB
interconnections to signal lines with
amplitude- and phase-matched interconnections,
such as microstrip, stripline, or
coplanar-waveguide (CPW) transmission
lines within the PCB and coaxial cable
assemblies between multiple PCBs. The
transmission lines require suitable isolation
to minimize crosstalk between
channels as well as spurious and harmonic
signal generation, and low
enough loss characteristics to support
effective thermal management and minimum
electrical performance degradation
due to temperature variations.
Examining Examples
How much functionality is available
for an A&D system from a single SiP?
Two miniature systems from Analog
Devices demonstrate the impressive
functional capabilities from a single
packaged device. Model ADRV9002 SiP is
a mixed-signal, 2 transmitter × 2 receiver
transceiver SiP with complete receiver
and transmitter subsystems capable of
channel bandwidths from 12 kHz to 40
MHz across a frequency range of 30 MHz

equipment. (Image: Analog Devices)
to 6 GHz. It is housed in a 12 × 12 mm,
196-ball CSP_BGA package (Fig. 1). This
transceiver SiP is fully programmable via
a four-wire serial peripheral interface
(SPI) and is available with optional
low-voltage differential signaling (LVDS)
and CMOS synchronous serial data
interfaces. Its mixed-signal architecture
(Fig. 2) provides linear direct conversion
of radio signals, aided by quadrature
error correction (QEC) and programmable
