Description
Positive Supply Voltage
Power Ground
Schmitt-triggered logic input. A LOW shuts down the whole
chip for battery saving purposes. A HIGH enables the chip.
Schmitt-triggered Band Select pin. When BS = H, channel 1
(OUT1) is selected, when BS = L, channel 2 (OUT2) is
selected.
RF Input connected to the Coupler output with optional
attenuation to measure the Power Amplifier (PA) / Antenna
RF power levels.
Sets the RF output power level. The useful input voltage
range is from 0.2V to 1.8V, although voltages from 0V to V
DD
are allowed.
Connects an external RC network between the Comp1 pin
and the Comp2 pin for an overall loop compensation and to
control the closed loop frequency response. Conventional
loop stability techniques can be used in selecting this
network, such as Bode plots. A good starting value for the
RC combination will be C = 68 pF and R = 0
.
Frequency compensation pin. The BS signal switches this pin
either to OUT1 or to OUT2.
This pin is connected to the PA of either channel 1 or
channel 2.

Note:
1. All inputs and outputs are referenced to GND (pin 10).
2. For the digital inputs, a LOW is
<
0.8V and a HIGH is
>
1.8V.
3. RF power detection is performed internally in the LMV242 and only an RF power coupler with optional extra attenuation has to be used.
