The HePA850 amplifier is a high power, RF amplifier intended to provide signal amplification and conditioning. The HePA850 amplifier is compatible with GSM and EDGE air interfaces operating in U.S. domestic cell sites where FCC compliance is mandatory. The Cell band (869 MHz to 894 MHz) HePA850 RF power amplifier is capable of amplifying a single carrier of different modulation types to a composite power level of 60Watts. HePA850 Specifications The HePA850 provide linear amplification of single-carrier signals in the cellular frequency band. The HePA850 have the following specifications: Parameter Specification Operating RF Band 869-894MHz In band RF gain 48dB (Tolerance ±2dB) Input signal types GSM or EDGE single carrier Bandwidth 20dB Pass Bandwidth ( Duplexer applied): 32MHz Occupied BW: GSM 248KHz & EDGE 245KHz Input DC Power -48 VDC, nominal DC voltage input range -38VDC to -58.5VDC Input/Output Connector 50 Ohm /50Ohm Rated Output Power @ -38VDC to -58.5VDC input 60W average for GSM/ 45W average for EDGE DC-RF Efficiency 28%, rated output power, nominal input voltage Physical dimensions 10” x 14” x 3” Weight < 15lbs Cooling technique External cooling when the Amplifier is placed in the customer frame. Temperature Range 0°C to +60°C meeting specifications. Table 1 HePA850 Specifications Functional Blocks: The Andrew HePA is comprised of the following functional areas: − Preamplifier with unit gain control This block gives to the unit its specified gain through 3 amplifier stages and helps keeping this gain constant over temperature through a variable attenuator, this one being controlled by the controller circuit. − Amplifier power Final stage RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 3 of 3 This stage brings the signal to its desired high power level, it is the heart of the RF section of the unit. The unit power, linearity and efficiency directly come from this block. − Power conversion and conditioning circuit This block is made of a DC/DC converter and various voltage regulators to do the interface between the customer supply network and the internal functions of the unit. It provides all the voltages and signal interface to the internal blocks of the unit. − Controller circuit This block is the “intelligence” of the unit, it is based on the CPU and computes all the internal functions of the unit. These are the power up sequences, the performances compensation over temperature, manages the monitoring and control of the unit, it also records many events in the so called flight recorder . − Communications circuit The communication circuit is associated to the controller circuit to communicate with the outside world. It handles the customer specific protocol to bring in and out all monitoring and control commands. Figure PA Configuration Analogical interface Power Supply distribution. Current measurement -48V power supply Analog interface RF PART RF input Power detector RF Output RF Power Amplifiers Andrew Corporation – Power Amplifier Group Propriety – Use pursuant to Company Instruction 4 of 4 Inputs and Outputs: The amplifier is powered from a DC supply voltage, which can range from -38VDC to - 58.5VDC. The DC power is brought into the amplifier through a D-Sub connector located on the face plate of the amplifier. A second multipoint connector located on the amplifier face plate is used for serial communication, monitoring and control. This connector is used both during factory tests and at the system level by the customer . Alarms and operating state are communicated to the outside world through the serial communications bus and through the face plate LED. The RF signal is brought into the amplifier through a female SMA type connector located on the face plate of the amplifier. The amplifier RF signal is brought out of the amplifier through a N type connector located on the face plate of the amplifier. Control System: A microprocessor controller is used to control the amplifier alarm system, control environmental compensation of the amplifier.

Installation and Operation Set-Up The HePA850 is easy to operate and use, only requiring a special cables for DC power and serial bus control connection into the customer frame. RF input and output connections are done with industry standard SMA and N connectors. FCC Statements : FCC ID: S8L-100306HEPA This devise complies with Part 2, 15 & 22 of the FCC Rules.

The below is the answer for your questions: Compliance Certification Services <[email protected]> wrote: Wei Li, I have reviewed the above referenced TCB application and find that the following items need to be addressed before the review can be completed: 1. The request for Confidentiality submitted with this application was one generated for Industry Canada. Please submit a Request for Confidentiality for the FCC/TCB application if you wish for portions of this application to be held from public view. Please change the letters in FCC and IC applications. I just misplaced them. 2. The Users Manual statement of compliance indicates that this device is in compliance with FCC Pt. 24, when this device has been submitted for certification to FCC Pt. 22. While the statement of compliance with Pt. 22 is not required by the FCC (only Pt. 15 requires this statement) including Pt. 24 in this statement is confusing. Please either remove the reference to Pt. 24 or change it to reference Pt. 22. Please see the revised manual ( I uploaded the old one. sorry) 3. The test data for band edge spurious emissions compliance used signals at 869.4 and 893.6MHz, which are one channel removed from the band edges for this band (we would expect data for 869.2 and 893.8 MHz for full band). Please confirm that the actual band of operation with supporting data. Per applicant's technical spec.: the e xtreme end of the band is not use, e.g. the first and last channels are not used for actual RF transmissions. Tx band: 869.4 -893.6MHz. The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information within 30 days of the original e- mail date may result in application dismissal and forfeiture of the filing fee. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the e-mail address listed below the name of the sender. Best regards, Chris Harvey charvey [email protected] This replys are also applied to its IC application. Please let me know if you need any info. Thank again. Wei Page 2 of 2 1/17/2006
