Broadband, Small-signal Amplifier
The model PE1-38-0218-12/-6V-SFF 2 to 18 GHz amplifier is capable of gains of more than 40 dB. The unit's noise figure is 5.5 dB (max) from 2 to 14 GHz and 6 dB (max) from 14 to 18 GHz. SWR is 2 (max), P1dB is 13.5 dBm and IP3 is 22.5 dBm. Bias supplies are +7 to +15 V DC at 350 mA (max) and -6 to -15 V DC at 30 mA (max) The amplifier utilizes MMIC technology for unit-to-unit conformity and is supplied in an industry-standard package measuring 0.56" x 1.08". The unit can be used by itself for drop-in capability or with the supplied SMA connectors.
Planar Electronics Technology,
40 GHz Amplifiers
The models 25T18G26, 25T26G40, 40T18G26 and 40T26G40 amplifiers offer 25 or 40 W minimum power and frequency response from 18 to 26.5 GHz or 26.5 to 40 GHz. The units are self-contained, forced-air-cooled, broadband TWT instruments designed for use in applications that require instantaneous bandwidth, high gain and moderate power output. Front-panel digital display offers extensive operational control and system status information. Standard features include built-in IEEE-488 interface, 0 dBm input, SWR protection and gain control. Prices: $100 K each for the 25T models and $125 K each for 40T models.
The model L5964 personal communications service (PCS) diplexer/amplifier is designed for use in high performance, low loss applications. The diplexer design utilizes two separate five-section coaxial cavity bandpass filters and two coupled zeros for high Q and low insertion loss. The integrated assembly has lower noise, lower return loss and a smaller package size than is possible with discreet components. The unit operates in the A-, B- and C-bands from 1850 to 1990 MHz with an insertion loss (TX) of 0.9 dB (max) (0.8 dB (typ)); gain (RX) of +12, +25, +35, +45 and +/-2 dB; noise figure (RX) of 2 dB max (1.8 dB (typ)); SWR of 1.5; and operating temperature of -50° to +70°C.
160 W MMDS Power Amplifier
This 160 W multichannel multipoint distribution system (MMDS) GaAs FET power amplifier operates from 2.5 to 2.7 GHz over a 200 MHz bandwidth and is provided in a small package. The class A amplifier includes over-voltage, reverse polarity and over-temperature protection. An output isolator is also integral to all designs, ensuring safe operation into open and short circuits. Additional standard features include RF enable/disable, sampled -40 dBc RF output, gain of 59 dB (min), 1 dB compression point (P1dB) of +51.7 dBm (min) (+52 dBm (typ)) and third-order intercept point (IP3) of +63 dBm (typ). Size: 9.0" x 13.0" x 1.5" (without heatsink).
Chesapeake Microwave Technologies Inc.,
Glen Rock, PA
(717) 235-1655, ext. 112.
The ABIT series amplifiers offer built-in test features for monitoring the power output. In addition to the RF output, the units include a detected TTL-compatible output with a threshold that can be externally adjusted via a variable voltage source. The amplifiers are supplied in a hermetically sealed Kovar package, which allows them to meet rigorous military and space environments. The units are available with various electrical options and an assortment of connector combinations.
RF Pulse Amplifier
The model LP1000UE broadband RF pulse amplifier is primarily designed for use in MRI laboratories. The system provides more than 1000 W pulse power over the frequency range of 200 to 500 MHz with a power gain of 60 dB (min). No tuning, band switching or adjustments are required to operate the system. General-purpose interface bus control is available with the optional IF-488 interface unit. The amplifier features forward and reflected power indication on a front-panel analog meter, automatic level control, RF gain control, overdrive protection, full SWR protection, input blanking and over-temperature protection. These features along with power on/off control are accessible for remote operation through a 25-pin, D-subminiature connector mounted on the rear panel.
Kalmus, a Thermo Voltek company,
High Power, Solid-state Ka-band Amplifier
The model AMPA131 amplifier is designed for use in LMDS and Ka-band satellite communications systems, and operates over a frequency range of 24 to 31 GHz. The unit features a power output of 10 W at P1dB and 60 dB of gain. Typical input and output SWR is 1.75 and the operating voltage is 48 V DC at 2.5 A. Available options include power monitoring and control via an RS485 serial port, output SWR protection and automatic gain control. Additional models are available with power levels up to 30 W.
