1 Introduction
A5135-H is an antenna module with SiRFstarV Flash based chip and an on-board
patch antenna (15mm x 15mm x 4mm). RF switch was implemented so as to sup-
port external active antenna for performance enhancement if required. In order to
have an easier migration for existing customers using A2235-H, we decided to keep
same pin assignment as that of A2235-H. Additional pins for supporting external
antenna won’t affect this drop-in replacement property. Since there is an RF feed
point underneath the module, special PCB design is required on user’s application.
The A5135-H is a module designed for a 3.3V environment.
1.1 Feature Overview
The A5135-H is a new module with the following outstanding features.
•Fast, responsive location experience
oHigh-sensitive navigation engine with tracking down to -165dBm
o52 track verification channels
oSBAS (WAAS, EGNOS, MSAS, GAGAN)
oConcurrent tracking of multiple constellations of the GPS and
GLONASS systems
•Breakthrough micro power technology
oRequires only 50 – 500µA to maintain hot start capability
•Active jammer remover
oRemoves in-band jammers up to 80dB/Hz
oTracks up to eight CW (continuous wave) jammers
•Size: 17.8mm (L) x 16.5mm (W) x 7.1mm (H)
•Operating voltage: 3V3
•Extremely low power consumption by using DC/DC converter
•No back-up battery required
•TCXO is used for providing stable 26MHz system clock
•Support external active antenna
•Support SGEE and CGEE
•Build-in LNA with close to 20dB for the integrated patch antenna

1.2 Characteristics Overview
The module’s most important characteristics are:
•A5135-H
oOperable at 3.3V / 34mA @ 1fix per second
oUART interface at CMOS level
oV_BAK at 3.0V / 60uA (typ.)
•Internal Power-On-Reset (POR) reset chipset to prevent memory corruption if
main power removal abruptly
•Internal 4 Mb SPI Flash
•Small form factor of 17.78 x 16.51 mm²(0.7” x 0.65”)
•Supported temperature range: -40°C to +85°C
•Single-sided SMT component, for reflow soldering
•RoHS compliant, lead-free
•Tape & reel packaging
•Excellent antenna support
oOn-module patch antenna
oAntenna input for direct connection of external active antenna
oRF switch to select between antennas
The antenna receiver module is available as an off-the-shelf component, 100%
tested and shipped in tape-and-reel packaging.
1.3 RoHS and Lead-Free Information
Maestro’s products marked with the lead-free symbol either on the module or the
packaging comply with the "Directive 2002/95/EC of the European Parliament
and the Council on the Restriction of Use of certain Hazardous Substances in
Electrical and Electronic Equipment" (RoHS).
All Maestro GPS+GLONASS receiver modules, GPS+GLONASS antenna receiver
module and telematics units are RoHS compliant.

1.4 Label
The A5135-H label (size: 12.0x 4.0 mm²) contains the following information:
TBA
Figure 1: A5135-H label
The label is placed on the side of the GPS+GLONASS antenna. The data matrix
code holds the product type, part number, software release, hardware release, fac-
tory code, year & week of assembly and a 6-digit serial number. Due to limited
space on module label, only product type, year & week of assembly and 6-digit serial
number will be printed on it.

Table 1: A5135-H GPS+GLONASS characteristics
(1) The calibrated clock of the receiver has not stopped, thus it knows precise time (to the µs level).
(2) The receiver has estimates of time/date/position and valid almanac and ephemeris data.
(3) The receiver has estimates of time/date/position and recent almanac.
(4) The receiver has no estimate of time/date/position, and no recent almanac.
Note: Performance (sensitivity and TTFF) might slightly decrease below -30°C.
