PE42660
Preliminary Specification
Evaluation Kit
The SP6T Evaluation Kit board was designed to
ease customer evaluation of the PE42660 RF
switch.
The PE42660 has two high power TX ports and four
high isolation RX ports. The TX ports are symmetric
and are designed as paths for the 850, 900, 1800, or
1900 MHz bands. The RX ports are also symmetric
and can be assigned to any of these frequency
bands.
The ANT port connects through a 50 Ω transmission
line to the top SMA connector, J1. The RX and TX
ports connect through 50 Ω transmission lines to
SMA connectors J2 – J7. A through 50 Ω
transmission line between SMA connectors J9 and
J10 allows estimation of the PCB losses over
environmental conditions. An open transmission line
connected to J11 is also provided.
J8 supplies DC power to the pin marked VDD and the
bottom row of pins, which is GND. 1 MΩ pull-up
resistors are connected from VDD to each of the three
control logic inputs: V1, V2, and V3. These pull-up
resistors are provided for ease of evaluation on this
board and are not required for the PE42660 to
operate.
Adding a jumper between a control pin and the
adjacent GND pin on the bottom row of J8 will set a
logic-0 on that control pin. Removing the jumper will
set a logic-1. To evaluate the PE42660, add or
remove jumpers according to the truth table in
Table 5.
