CDMA Power Amplifier
The model AWT6101 MIC CDMA power amplifier operates across the 1850 to 1910 MHz frequency range and has a low leakage of less than 10 mA, allowing extended standby times. Designed to minimize cycle time, save board space and reduce cost, the self-contained amplifier delivers linear operation up to +29 dBm with high efficiency of 32 percent and manages voltage turn-on and turn-off synchronization with a single interface pin. The amplifier is one of the first parts that incorporates the company's integrated DC-to-DC converter technology, which allows all of the benefits of GaAs devices without the need to supply negative voltage and additional supporting components in system designs. Size: 7 mm x 7 mm.

2.6 GHz 180 W Broadband Amplifier
The 180 W class A broadband wireless GaAs FET power amplifier, with a removable heat sink, operates from 2.4 to 2.7 GHz over any 200 MHz bandwidth. All units include over-voltage, reverse polarity and over-temperature protection. The amplifier provides minimum gain of 40 dB, maximum noise figure of 10 dB, input/output SWR of 1.5 (max) and typical IP3 of +66.5 dBm. An output isolator is also integral to all designs to ensure safe operation into open and short circuits, and RF enable/disable and a sample 40 dBc RF output are standard in all designs. Operating temperature range is 0° to +50°C. Size: 9.0" x 13.0" x 1.5", excluding heat sink.

Miniature Dual Log Amplifier
The model MCWL-4-4538 is a pair of matched miniature logarithmic amplifiers featuring log linearity of +/-0.75 dB (typ) and a standard center frequency of 200 MHz with an operating bandwidth of at least 20 MHz. The log video slope is 25 +/-1.5 mV/dB measured over the input signal range of -67 to +3 dBm (typ). SWR is less than 2.0, limited output power is 0 dBm (nom) and channel-to-channel isolation between pairs is specified at 50 dB (min). The unit requires a power supply of +/-5 or +/-6 V with total consumption of approximately 2 W and is housed in a dual flatpack with a surface area of approximately 1.3 in2. Mounting is accomplished via four through-hole threaded flanges. Price: $2950 (5-9).
