Device Overview
General Description
The ADM-0012-5931SM is a small, low power, and economical T3 driver or T3A pre-amplifier. It is a GaAs PHEMT distributed amplifier in a 3mm QFN surface mount package. The ADM-0012-5931SM can provide LO drive for ‘L’, ‘M’, ‘I’, and ‘H’ level mixers, with 11.5 dB typical gain and +19 dBm typical saturated output power for only 85 mA of current. The amplifier can be biased with internal circuitry, or with an external bias network for lower voltage and single supply operation.
Features
- Optimized for use as a T3 LO buffer amplifier
- 3rd and 5th Harmonic Generation
- Suitable for driving L, M, and I diode mixers
- Optional Positive Only Bias or Internal Bias Operation
- Broadband 50 Ω Matching
- Unconditionally Stable
Applications
- Electronic warfare equipment
- Test and Measurement Equipment
- Amplification Clock Signals
