General Description
The ACPF-7003 is a high rejection full band transmit  l-
ter designed for US PCS handsets. Its performance rivals
splitband surface acoustic wave (SAW) transmit  lters.
Since a single  lter provides the rejection, no switches
are required, saving board space and external compo-
nents, eliminating switch loss, and reducing program-
ming complexity. Furthermore, with 25dB rejection at
1830 MHz, it is a true split band replacement.
The ACPF-7003 FBAR transmit  lter utilizes Avago Tech-
nologies’ Microcap bonded-wafer chip scale packaging
technology. This process allows the ultra small  lters
to be assembled into a Molded Chip on Board (MCOB)
Module.
In typical cellular phone architectures, the transmit  lter
ts between the driver ampli er and the power ampli-
er. This  lter reduces the noise in the Rx band being
ampli ed by the transmit chain, enhancing receiver sen-
sitivity. High rejection keeps unwanted signals out of
the receive path.
Avago Technologies’ thin-Film Bulk Acoustic Resonator
(FBAR) technology makes possible high-Q  lters at a
fraction their usual size.

Notes:
1. Temperature is de ned at case TC, the temperature of the underside of the  lter where it makes contact with the circuit board.
2. Speci cations are guaranteed over the given temperature range. Operation in excess of any one of these conditions may result in permanent
damage to the device.

PCB Interface & Mounting instructions
Mounting Consideration and board description
The ACPF-7003 FBAR  lter has one input (Pin 1), one output (Pin 3) and two grounds (Pins 2 and 4.)
Demo board uses 3 mil Getek Microstrip.
The demo board uses CPWG transmission lines for high isolation between the two ports. It uses via holes to connect
the CPWG line from the underside of the board to the  lter mounting pads on top.
Note: For best performance, try to reproduce this board stack up closely. If Ground-Signal-Ground (GSG) type board is used, better return loss can
be achieved since it eliminates connector mismatch.
Demo boards
Demo boards are available for sampling. (See board drawing in Figures 7, 8, and 9.)
