VccBat
Battery connection
Amplifier DC supply voltage pin. This supply can be
connected directly to the unregulated battery voltage.
External decoupling capacitors are typically required.
17
cdmaOutSel
PCS band select
DC input, toggles CDMA amplifier output between cdmaOut1
(pin 22) and cdmaDrvOut2 (pin 19). A logic 1 selects
cdmaDrvOut1, and a logic 0 selects cdmaDrvOut2. At a logic
high, this pin draws less than 3
μ
A. At a logic low level this pin
sources 1
μ
A.

cdmaDrvOut2
CDMA Amplifier
output #2
CDMA RF output from amplifier stage.
An external connection
to VccBat is required. CdmaOutSel is used to enable either this
pin or the cdmaDrvOut1.

cdmaDrvOut1
CDMA Amplifier
output #1
CDMA RF output from amplifier stage.
An external connection
to VccBat is required. CdmaOutSel is used to enable either
this pin or the cdmaDrvOut2.

Mode select
DC input, Selects between AMPS and CDMA modes. A logic 0
selects AMPS mode, while a logic 1 selects PCS CDMA mode.
See Table 1 in the
Theory of Operation
section for more
information. At a logic high, this pin draws less than 3
μ
A.
At a logic low level this pin sources 1
μ
A.
Amplifier DC supply voltage pin. This supply can be
connected directly to the unregulated battery voltage.
External decoupling capacitors are typically required.

pwrDn
Power down
DC input, a logic low will power down the HPMX-7201, a logic
high turns the IC on. This input controls the bias cell of the
HPMX-7201, allowing it to shutdown all sections of the chip
regardless of which Vcc supply (Vcc or VccBat) the section
uses. At a logic high, this pin draws less than 30
μ
A. At a logic
low level this pin sources less than 1
μ
A typically.
Amplifier DC supply voltage pin. This supply can be
connected directly to the unregulated battery voltage.
External decoupling capacitors are typically required.

Vcc
Regulated DC
Voltage connection
Regulated Vcc connection to IC mixer circuits, separated from
amplifier supply voltage to avoid non-linear mixer effects due
to supply coupling.

ampsDrvOut
AMPS amplifier
output
AMPS RF output from amplifier, an external connection to
Vcc is required

32
ampsDrvIn
AMPS amplifier
input
Input to AMPS amplifier. Internally AC coupled. A matching
circuit is required for operation from a 50
source impedance.
