Evaluation Board Description
The SE2600S Evaluation Board is used to test the performance of
the SE2600S LNA FEM. An Evaluation Board schematic diagram is
provided in Figure 3. Table 9 provides the Bill of Materials (BOM)
list for Evaluation Board components. An assembly drawing for the
Evaluation Board is shown in Figure 4.
Evaluation Board Setup Procedure
Step 1: Connect system ground to pin 1 of the J14 header.
Step 2: Apply 3.3 V to pin 14 of the J14 header.
Step 3: Select a path/mode according to the information in
Table 8. For the J14 header pinout, refer to the Evaluation
Board silkscreen and schematic in Figure 3.
NOTE: In case only three controls are available from the
application, (transmit, receive, and Bluetooth), connect the
VC2 and VON signals together. In this configuration, the
LNA is always “on” in receive mode (corresponding to high
gain mode in Table 8). The LNA 3
rd
Order Input Intercept
Point (IIP3) is > +5 dBm.
Evaluation Board Losses
The board losses from the RF connectors of the Evaluation Board
to the pins of the SE2600S are:
RFC: 0.175 dB
TX: 0.165 dB
RX: 0.175 dB
BT: 0.21 dB
Package Dimensions
The PCB layout footprint for the SE2600S is provided in Figure 5.
Typical case markings are shown in Figure 6. Package
dimensions for the 11-bump WLCSP are shown in Figure 7, and
tape and reel dimensions are provided in Figure 8.
