Description
Bias circuit and HDET power supply. A low frequency decoupling
capacitor (2.2 F) is required. Type: P
Ground connection. Connect to the GND_SLUG pin. For best perfor-
mance, keep traces physically short and connect immediately to
ground plane. Type: P
Ground connection. Connect to the GND_SLUG pin. For best perfor-
mance, keep traces physically short and connect immediately to
ground plane. Type: P
RF input internally matched to 50 . This input is internally AC-coupled.
Type: A, I
First stage power supply. A low frequency decoupling capacitor (2.2 F)
is required. Type: P
Output stage power supply. A low frequency decoupling capacitor
(2.2 F) is required. Type: P
RF output internally matched to 50 . This input is internally AC-cou-
pled. Type: A, O
Ground connection. Connect to the GND_SLUG pin. For best perfor-
mance, keep traces physically short and connect immediately to
ground plane. Type: P
Ground connection. Connect to the GND_SLUG pin. For best perfor-
mance, keep traces physically short and connect immediately to
ground plane. Type: P
Power detector output. Type: A, O
Gain step control. When this pin is High, the module is in low power
mode, and the amplifier’s current is reduced. When this pin is Low, the
module is in high power mode. Voltage should not be applied to this pin
before VCC3 is applied. Type: D, I
Device enable control. When this pin is High, the device is on. When
this pin is Low, the device is off. Voltage should not be applied to this
pin before VCC3 is applied. Type: D, I
Ground connection. The backside of the package should be soldered to
a top side ground pad which is connected to the ground plane with mul-
tiple vias. The pad should have a short thermal path to the ground
plane.
