MBF9045BB
SAW Antenna Duplexer (700 to 1000 MHz)
1/10
GENERAL DESCRIPTION
The MBF9045BB is the SAW antenna duplexer for the frequency range of 700 to 1000 MHz.
This SAW Duplexer integrates RF filters at Tx and Rx side, and matching circuit into PKG. This helps to save the
space and weight greatly in the target application such as mobile telephone.
This SAW Duplexer has very low insertion loss by using high quality package.
Due to high harmonics characteristics, total number of components at RF circuit can be minimized.
Thanks to high isolation performance, high sensitivity can be expected. Low insertion loss at Tx saves the power
consumption of mobile telephone which prolong the battery life.

RECOMMENDATION FOR SOLDER PAD PATTERN
The solder pad pattern should be designed by customers because it depends on the electrical
performance of the customers' system. Following is an example of solder pad pattern which is used in
OKI's package evaluation board. Please be noted that this is for reference purpose only.

Pad of Device
Please pay attention to the following items to maintain electrical performance.
(1) Metal mask pattern for cream solder should be 25
m smaller on each side. Metal mask is 0.15 mm in
thickness.
(2) As the impedance of Tx, Rx, ANT is designed for 50
, please consider this for the design of mother board.
