Microcell 30 The Microcell 30 (M30) Broadband Transmit Amplifier delivers 30 Watts of composite multicarrier power at cellular frequencies. It is compatible with AMPS,CDMA and TDMA air interfaces and represents the latest in second generation Power Amplifier design. It is suitable for applications that require simultaneous amplification of different formats e.g. AMPS and TDMA. It an ideal amplifier for microcell application. The feedforward design of the M30 ensures low levels of intermodulation. . It is available for 110VAC, 220VAC, 20 to 28VDC or a nominal –48VDC operation. It has 1 to 3 inputs available at the front panel connections for the main cabinet transmit combiner output and one or two auxiliary cabinets. The M30 incorporates field replaceable fans and remote shutdown capability. A field replaceable input module allows connector interface and/or gain change. The Microcell 30 is well suited for new system specification. It is also available as a reliable alternative to the popular Ericsson 882 series MCPA. M30 MCPA          View Specs »

Microcell 40 The M40 amplifies the low power, combined outputs of cellular base station Microcell transceivers and presents the composite 40 Watt multichannel output to the antenna feed. The compact package makes this product ideal for installations that require a physically small base station having channel output powers higher than those available from standard Microcell equipment. The M40 is available for AC or DC operation and it includes all the features necessary for a quick and effective installation. The optional outdoor enclosure is suited for weather exposed installations. A Link Balancer (low noise receive amplifier is available for systems that require additional receive sensitivity to ensure balance between forward and reverse links. The M40 is a member of the AML Communications family of multicarrier amplifiers providing composite output powers of 4 to 140 Watts. M40 MCPA          View Specs »     Microcell 80 The Microcell 80 (M80) Ultra linear Cellular Multicarrier Power Amplifier (MCPA) provides 80 watts of composite power with a typical channel loading of 21 channels at 3.8 Watts each. The broadband nature of this amplifier allows flexibility of frequency allocation and eliminates the need for individual channel amplifiers plus their associated cavity autotune combiners. An additional feature is the inclusion of a dual diversity pair of Low Noise Amplifiers (LNA) to facilitate a balanced reverse link. This transmit/receive amplifier supports analog and digital transmission standards including AMPS, TDMA, GSM, and CDMA. The unit is presented in a 19 inch rack mount chassis that includes power supplies, fans and an alarm interface. M80 MCPA        Microcell 140 The M140 delivers the highest output power in the AML Communications family of multi-carrier power amplifiers. With 140 Watt composite power, it achieves the ERP levels required for "core" base station cell sites. By amplifying the low power, hybrid combined outputs of microcell transceivers the M140 enables physically small base station equipment packages that provide areas of coverage similar to that of much larger traditional base station. The high power feedforward design of the M140 ensures high levels of intermodulation cancellation without incurring runaway current consumption or extraordinary levels of contributed heat. A Link Balancer (low noise receive amplifier is available for systems that require additional receive sensitivity to ensure forward and reverse link balance.
