Key Features
- High IP3 performance handles input power up to 27 dBm, enabling use in high-power RF front-end receive chains without compression
- Frequency coverage from 1700 MHz to 2400 MHz targets LTE Band 2/4 and 2.4 GHz ISM band designs in a single part
- Compact MSOP-8 surface-mount package simplifies PCB integration compared to discrete mixer topologies in space-constrained RF modules
Applications
HMC485AMS8GE is used in base-station and small-cell receiver front-ends operating in the 1700 MHz to 2400 MHz range, where high dynamic range is critical to handle strong interferers alongside weak desired signals. It is also suitable for test-and-measurement equipment such as spectrum analyzers and signal generators that require a high IP3 mixer stage. Military and aerospace communication systems benefit from its robust 27 dBm input power handling and surface-mount construction.

Frequently Asked Questions
What frequency range and maximum input power level does HMC485AMS8GE support in a receiver front-end?
HMC485AMS8GE operates from 1700 MHz to 2400 MHz and accepts continuous-wave input power up to 27 dBm. This combination makes it suitable for high-power RF receive paths such as LTE Band 2 or 2.4 GHz ISM receivers where strong interferers must be handled without driving the mixer into compression.
How does the conversion loss specification of HMC485AMS8GE affect system noise figure budget in a superheterodyne design?
HMC485AMS8GE specifies a maximum conversion loss of 11 dB, which adds directly to the system noise figure in a superheterodyne chain. Designers typically follow the mixer with a low-noise IF amplifier having a gain of at least 15 dB to recover sensitivity; the high IP3 ensures the 11 dB loss is a worthwhile trade-off for linearity.
Why is an MSOP-8 package preferred over a DIP or SMA-connectorized module for HMC485AMS8GE in production PCB designs?
The MSOP-8 package occupies less than 30 mm² of PCB area and is reflow-solderable, enabling automated pick-and-place assembly at production volumes. A connectorized module would require at least 400 mm² and manual assembly, raising cost and adding connector-transition losses at 2400 MHz.
When is HMC485AMS8GE a better choice than a silicon RFIC mixer for LTE infrastructure applications?
GaAs-process parts like HMC485AMS8GE achieve higher IIP3 and lower intermodulation distortion than typical silicon RFIC mixers at 1700 MHz to 2400 MHz, which matters in multi-carrier base stations handling 20 MHz channel bandwidths. Silicon alternatives may suffice at lower input power levels below 10 dBm but can compress earlier, degrading EVM in wideband LTE signals.
