MODEL AY-F45S, Multicoupler Assembly

The Multicoupler Assembly, Model AY-F45S, contains six (6) multicpupler modules and a power/ supervisory module. The mulitcoupler has two cascaded MMIC low noise amplifiers with high dynamic range and a microstrip output two (2) way power divider. There are six multicoupler modiles in a lowprofile package made to fit into a 19 inch rack or alternate location outside the rack using brackets.

MODELS DCF-A01 & DCF-A02, CDMA/GSM Filter Combiner

These units are designed for CDMA and GSM applications where it is used to combine high power transmitter signals to a common antenna port. Our combiner series offers substantially smaller size, improved insertion loss and other RF performance
that is superior to competing designs.

• Cavity Low Loss Diplexer Design
• High Input Port Isolation
• High Power Handling
• Custom Designs & Configurations
  available upon request

This High Power PIN diode switching is used in the custom matrix assembly, to switch four (4) GSM transmitters to a Smart antenna System. Power levels of 50 watts per input can be switched to any of (8) outputs in any combination, with low IM performance. The unit also includes forward and reverse power and antenna monitoring functions.

Model AY-G63S Imbedded Test Transceiver/Monitor
for Base Stations

Aeroflex / KDI subassemblies function as a CDMA test radio, that monitors the integrity of the antenna for the transmit and receive path's in a base station . An internal phone module acts as a consumer mobile phone, that places a call through a live cell site at scheduled intervals. Both Cellular and PCS frequencies are provided as needed in these custom products.

Model AY-G50S Bandpass Filter/ LNA, Cellular Applications

The MCE/KDI Filter/LNA will enhance CDMA network performance, by providing the ability to communicate with and successfully hand – off mobiles that were previously “in the noise”, while significantly extending the battery life of the mobile. Base stations that have reverse link limitations due to frequency interference problems and need of gain improvement, stand to benefit by using this BPF/ LNA.

Model BY-1911S, Clock Amplifier for Optical Driver
@ 10.66 GHz

The Model BY-1911S is a sub-assembly, consisting of amplifiers, gain control, (2) phase shifters, and a clock bias and modulation input circuit. The primary application is use as a driver input of a Lithium Niobate optical modulator.

Model CL-K59S Dual Directional Coupler...

The Model CL-K59S was designed for a custom application in the transmitter path for base station applications. The frequency range was limited only by the particular system it was made for; wider frequency bandwidth's and ranges are available as may be needed for other applications.

MODEL FEU-WCDMA1 WCDMA RF Front End Unit...

Designed for WCDMA applications, this RF Front End unit consists of a diplexer, a dual directional coupler, an LNA and a four-way power divider. This high performance, compact module is designed for base station transceiver applications and delivers stable performance over an operating temperature range from
-20°C to 70°C.

• Compact Integrated Package
• High Rx Input Intercept Point
• High Isolation between Tx and Rx
• Dual Coupler to Monitor Forward & Reflected Power

Vector Modulators for MCPA Applications...

KDI's surface mount vector modulators are typically used in MCPA's tp adjust phase and amplitude setting to achieve low intermod and exceptional linearity performance. The PIN diode controlled units provide 0-360 degree phase adjustment range, with a minimum attenuation range of 0-14 dB.

• All bias circuitry components are included.
• Surface mount package suitable for re-flow soldering and aqueous cleaning.
• Reliable and cost effective thick film hybrid technology.
• Standard models covering 400-3000 MHz frequency range.
• Supplied on tape or reel.
