High Linearity Broadband SP2T

30MHz to 6GHz

F2977

Datasheet

Description

Features

The F2977 is a 50ꢀ singleꢁpole doubleꢁthrow (SP2T) reflective RF

switch featuring high linearity and wide bandwidth. This device is

optimized from 30MHz to 6GHz to support a multitude of wireless

RF applications. The F2977 uses a single positive supply voltage

of either +3.3V or +5.0V and is compatible with either 1.8V or 3.3V

control logic.

ꢀ

Low insertion loss:

ꢀ 0.38dB at 2.4GHz

ꢀ 0.45dB at 6GHz

ꢀ

High Isolation:

ꢀ 39dB at 2.4GHz

High Linearity:

ꢀ IIP2 +125dBm at 2.4GHz

ꢀ IIP3 +77dBm at 2.4GHz

P0.1dB compression of +40dBm at 2.4GHz

Second Harmonic: ꢁ95dBc at 900MHz

Third Harmonic: ꢁ90dBc at 900MHz

Supply voltage: +2.7V to +5.25V

1.8V and 3.3V compatible control logic

Competitive Advantage

The F2977 provides extremely low insertion loss across the entire

bandwidth while providing superb distortion performance.

Application Information

Power Supplies

A common V_CCpower supply should be used for all pins requiring DC power. All supply pins should be bypassed with external capacitors to

minimize noise and fast transients. Supply noise can degrade noise figure and fast transients can trigger ESD clamps and cause them to fail.

Supply voltage change or transients should have a slew rate smaller than 1V / 20ꢃs. In addition, all control pins should remain at 0V (+/ꢁ 0.3V)

while the supply voltage ramps up or while it returns to zero.

Control Pin Interface

If control signal integrity is a concern and clean signals cannot be guaranteed due to overshoot, undershoot, ringing, etc., the following circuit

at the input of each control pin is recommended. This applies to control pins 7 and 8 as shown below.

External Supply Setup

Set up a V_CCpower supply in the voltage range of +2.7V to +5.25V with the power supply output disabled.

Connect the disabled V_CCsupply connection to J6 pin 3 and GND to J6 pin 1, 2, 4, 6, 8, 9, or 10.

Logic Control Setup

With the logic control lines disabled, set the HIGH and LOW logic levels to satisfy the levels stated in the electrical specifications table.

Connect the disabled logic control lines to J6 EN / LS (pin 5) and V_CTL(pin 7).

See Table 8 for the logic truth table.

Turn On Procedure

Setup the supplies and EVKit as noted in the External Supply Setup and Logic Control Setup sections above.

Enable the V_CCsupply.

Enable the logic control signals.

Set the logic setting to achieve the desired Table 8 configuration. Note that external control logic should not be applied without V_CCbeing

present.

Turn Off Procedure

Set the logic control pins to a logic LOW.

Disable the V_CCsupply.
