Dear Barry, Following are my responses to the issues raised. Regards, Tom ---------------------------------------------------------------------------- Dear Tom, We have conducted our review of the application. The following issues need to be resolved before we can proceed: 1. The spurious radiated data is taken utilizing a procedure similar to ANSI C63.4. This will not be acceptable in the future and may not be acceptable now. The FCC has stated that it is branch policy to require the measurements be made in accordance with ANSI/TIA/EIA-603-1992 Section 2.2.12 substitution method. We believe that the FCC has expressed some clemency and will accept a few more applications with test data taken in this mode, but they could decide not to accept non-substitution data at any time. In light of these developments, you may wish to submit substitution based measurements for this device. Response: This is an issue that we dealt with back in 1990 in correspondence with the Commission. Since there was no test procedure specified at the time, we proposed that field strength measurements be made and the erp derived mathematically using Maxwell's equations. At that time they agreed to the proposal. We have no objection, however, to using the EIA method on future filings. 2. We do not see data for a three signal test in this application. We note that there is mention of a mode in which the device puts up four channels. We do see two signal tests for the various operating modes, but the FCC tells us that they want to see these performed at the band edge (both high and low). If you can't do three signal tests due to equipment limitations it is acceptable to perform the two signal intermod test at the upper and lower band edges. Please submit plots responsive to this request. Response: The two-signal intermodulation tests were performed at lower, middle, and upper band and appear in the report on pages 30 - 35. Attached here is a plot of the intermodulation spurious with three analogue(voice) modulated signals. <<analog intermod.xls>> 3. Please submit a plot of the input vs. the output modulated waveform for each modulation type. Response: The input plots precede the output plots in the report. 4. Please report the DC voltages and currents in the final amplifier stage. Response: Power amplifier is a Stanford Microdevices SXA-289. It uses +5Vdc@ 115 mA. 5. Please submit the amplifier tune-up procedure. This may be a factory procedure used to set the unit's output power. Response: There is no tune-up procedure. The power output is limited by the rf cascade. 6. Please submit a document responsive to the 22.933 requirement for compatibility with OET 53. A statement will be acceptable. Response: The Commission has generally not required this attestation statement for amplifier products since the attestation is intended to address the operability of mobiles and base stations in the AMPS system and an amplifier product really has no impact on this. 7. Please supply a complete users manual so we can check for the necessary statements regarding modifications, compliance and RF exposure. Response: The manual is still in draft form but does include the necessary statements. <<InCell new manual.zip>>

Circuit Description Central Distribution Unit (CDU) The CDU is connected to a Repeater, BDA, or BTS via coaxial cable. The Downlink (Base-to- Mobile) transmit path is distributed to Remote Antenna Units (RAU). PDU card - The rf input signal is distributed to individual CDU cards (up to six per unit) via the Power Distribution (PDU) Board, which consists of simple passive power dividers. Also located on the PDU card is a pilot oscillator that simply generates a pilot tone that is filtered in the Remote Antenna Unit (RAU) and used to verify the rf link. This pilot tone is never transmitted wirelessly. CDU card - In the Downlink direction the CDU card consists of a SAW filter and rf to laser conversion module. Once the rf signal has been converted to light, it is distributed to a Remote Antenna Unit (RAU) via fiber cable. In the Uplink direction, the CDU card simply performs the opposite function. The optic signal fed from the RAU uplink output is converted to rf, amplified, filtered, and finally passed to the PDU card where it will be sent to the external repeater, BDA, or BTS equipment via coaxial cable. Remote Antenna Unit (RAU) In the Downlink direction, the RAU receives the optic signal from the CDU and converts it to rf. At this stage a Low Pass filter sends the pilot tone to a Pilot Detection Circuit, The intended transmit signal is sent through a two-stage amplifier/filter circuit. The resulting signal is fed through a passive duplexer and finally sent to an external antenna via coaxial cable. The external antenna gain is typically 12 dB maximum. In the Uplink direction, the RAU receives an rf signal from the mobile via the external antenna. The rf signal is processed through a filter/gain control circuit through to a rf-to-optic conversion circuit. The optic signal is the sent to the CDU via fiber optic cable.

This would guarantee that the antenna would never be closer than 20 cm to any person. To actually exceed the limit of .579 mW/cm 2 , the antenna unit would need to be closer than 10.4 cm. to any person.

This system is made up of two components: 1) CDU (Central Distribution Unit) - This unit is typically located in a wiring closet. Each CDU can interface to six RAU (Remote Antenna Units). The CDU collects and distributes voice and data signals through fiber cable pairs. The CDU connects to the output of a repeater unit. The Uplink direction is a directly wired connection and cannot connect directly to an antenna. The transmit signals from the repeater are converted from rf to optical and distributed via the fiber cables to a RAU. 2) RAU (Remote Antenna Unit) - This unit converts the signal received fr…
