ALM-2812-TR1G

ALM-2812
Dual-Band (2.4-2.5) GHz & (4.9-6) GHz
WLAN Low-Noise Amplier
Data Sheet
Description
Avago Technologies’ ALM-2812 is a dual-band LNA
designed for WLAN applications in the (2.4 - 2.5)GHz
and (4.9-6)GHz frequency ranges. The LNA uses Avago
Technologies proprietary GaAs Enhancement-mode
pHEMT process to achieve high-frequency wideband
operation with very low noise gures.
The ALM-2812 has two individual LNAs housed in a
3mm x 3mm package, each one switcheable using a
single CMOS-compatible pin. All matching components
are inside the module. Only one external low frequency
bypass capacitor is required for proper operation,
making it suitable for use in ultra-miniature WLAN cards
and access points.

Note:
5. Distribution data sample size is 18K samples taken from 3 dierent wafers and 3 dierent lots. Future wafers allocated to this product may have
nominal values anywhere between the upper and lower limits.
6. Measurements are made on production test board, which represents a trade-o between optimal Gain, NF, IIP3, IP1dB and VSWR. Circuit losses
have been de-embedded from actual measurements.

Notes:
7. The parameters with an indicated Production Limit (Production Min and Production Max) are tested at our production nal test with no
guardbanding. Production Limits are tighter than Customer Limits to serve as a guardband to guarantee the Customer Limits. Customer Limits
will have the following guardband: Gain =±0.5dB, NF=±0.2dB, Ids=±1mA
8. Production Limits are subject to change with customer consensus and approval. Pricing is subject to change based on yield impact.
