ACPM-7886
TD-SCDMA Power Amplifier
Data Sheet
www.DataSheet4U.com
General Description
The ACPM-7886 is an amplifier module designed for
TD-SCDMA applications in the 2010-2025MHz band.
Designed around Avago Technologies’ GaAs
Enhancement Mode pHEMT process, the ACPM-7886
offers premium performance in a very small form factor.
It is matched to 50 Ohms on the input and output.
The amplifier has excellent ACLR and efficiency
performance at max Pout and low quiescent current
(50mA) with a single bias control voltage, Vctrl = 2.0V.
Designed in a surface mount RF package, the ACPM-
7886 is very cost and size competitive.

ESD Sensitivity Level
Human Body Model (EIA/JESD22-A114B):
Class 1A (250Vmin, less than 500V)
Machine Model (EIA/JESD22-A115A):
Class A (50Vmin, less than 200V)
Notes:
ESD Sensitivity level for Human Body Model and
Machine Model necessitate the following
handling precautions:
1. Ensure Faraday cage or conductive shield bag is used during
transportation processes.
2. If the static charge at SMT assemble station is above the device
sensitivity level, place an ionizer near to the device for charge
neutralization purposes.
3. Personal grounding must be worn at all times when handling
the devices.
Moisture Sensitivity Classification: Class 3
Preconditioning per JESD22-A113-D Class 3 was
performed on all devices prior to reliability testing.
ACPM-7886 is a moisture sensitive component. It’s
important that the parts are handled under precaution
and a proper manner. The handling, baking and out-
of-pack storage conditions of the moisture sensitive
components are described in IPC/JEDC S-STD-033A.

Avago Technologies recommends utilizing the
standard precautions listed below.
1. Calculated Shelf Life in Sealed Bag: 12 months at <
40°C and < 90% Relative Humidity (RH)
2. Peak Package Body Temperature: 250°C
3. After bag is opened, devices that will be subjected
to reflow solder of other high temperature process
must be:
a. Mounted within 168 hours of factory condition
30°C / 60% RH
b. Stored at <10% RH if not used
4. Devices require baking, before mounting if:
a. Humidity indicator card is > 10% when read at
23 ± 5°C immediately after moisture barrier bag
is opened.
b. Items 3a or 3b is not met
5. If baking is required, please refer to J-STD-033
standard for low temperature (40°C) baking
requirement in Tape/Reel form.

Figure 8. Signal Studio configuration.
Technically the mobile will transmit on the uplink, but
the main point is to display the configurability for each
slot. In fact, the test for ACPM-7886 does not require
the full 16 code channels.
Signal Studio is most beneficial for a base station uplink
or downlink test where multiple users will be
transmitting on the same time slot. For this test only
one time slot is used with a single code.
