IN
DCS1800/PCS1900 RF input pin.
4
GND1
LNA1 emittance inductance. Total inductance is comprised of
package+bondwire+L2 on PCB.
5
VCC
Open collector for first stage LNA of DCS1800/PCS1900. It must be
biased to V
CC
through a choke or matching inductor.
6
GND2
LNA2 emittance inductance. Total inductance is comprised of
package+bondwire+L4 on PCB.
7
OUT
DCS1800 Amplifier Output pin. This pin is an open-collector output. It
must be biased to V
CC
through a choke or matching inductor. This pin
is typically matched to 50
with a shunt bias/matching inductor and
series blocking/matching capacitor. Refer to application schematics.
