Sanland’s AG50 is a high-performance InGaP HBT MMIC amplifier utilizing a Darlington configuration with an active bias network. The active bias network provides stable current over temperature and process Beta variations. Designed to run directly from a 5 V supply, the AG50 does not require a dropping resistor as compared to typical Darlington amplifiers.

The AG50 product is designed for high-linearity 5 V gain block applications that require small size and minimal external components. It is internally matched to 50 Ω.

Frequently Asked Questions

What is the frequency range of the AG50?

AG50 operates from 50 MHz to 4 GHz and is designed as a broadband RF and IF gain block.

What are the typical gain and linearity of AG50?

At 1.95 GHz, AG50 typically provides 19.6 dB gain, +19.6 dBm P1dB and +38 dBm OIP3.

Does AG50 require external 50 Ω matching?

AG50 is internally matched to 50 Ω. A typical application uses DC-blocking capacitors and an RF choke as shown in the reference circuit.

Can AG50 be used as an alternative to TQP3M9008, BGA6489, SGA6489Z or HMC589?

AG50 can be evaluated as an alternative for selected broadband gain block applications. Pin configuration, bias components, RF performance and PCB compatibility should be verified before replacement.

What information is needed for a cross-reference evaluation?

Please provide the original part number, operating frequency range, supply voltage, target gain, P1dB/OIP3 requirements and, if available, the existing circuit or BOM.

AG50 / RF PERFORMANCE

Typical RF Performance

Frequency	Gain	OIP3	P1dB	NF
850 MHz	20.8 dB	40.0 dBm	20.5 dBm	2.8 dB
1950 MHz	19.6 dB	38.0 dBm	19.6 dBm	2.8 dB
2500 MHz	19.1 dB	35.4 dBm	18.9 dBm	3.0 dB
3500 MHz	18.6 dB	31.3 dBm	16.5 dBm	3.1 dB
4000 MHz	18.4 dB	30.5 dBm	16.1 dBm	3.4 dB

TEST BASIS

Typical values are measured at V_S = 5 V, I_S = 80 mA and T_L = 25°C in a 50 Ω system. OIP3 uses 1 MHz tone spacing with +5 dBm output power per tone.
